SVG Format[edit]

Thank you so much for awarding me the chemistry bond star. I feel Wikipedia is an incredible resource for almost anyone, and continue to improve articles and identify vandals as best I can. I am curious as if you know how to create SVG files on the Macintosh platform. I've tried to use Inkscape, but haven't succeeded (the program does not launch, but simply quits upon so). The PNG files I've uploaded are high-resolution and, as I feel, as high-quality as Wiki articles would need. However, I am aware that SVG is the preferred format for chemical structures. Have you any suggestions regarding this matter? Secondly, is there a specific page on Wikipedia that identifies articles needing IUPAC naming and/or chemical structures of high-quality?

Not to worry[edit]

It's an easy mistake to make. Relax. :) Lewis Collard! (hai thar, wut u doin) 13:38, 2 June 2008 (UTC)

Protein structures[edit]

Hi, I took a look at the gallery and I'm very impressed with the protein structures. How do you make those? Do you have a 3D file for each one - what format? I think the lack of 3D on Commons is a great loss. Dhatfield (talk) 13:21, 26 June 2008 (UTC)

Strange SVG error[edit]

Hi there, any idea how to fix the text in this? 03:09, 18 July 2008 (UTC)

Yes check.svg Done. The author specified a typeface (Helvetica Neue) that isn't supported in MediaWiki, and since he didn't specify a font stack, the renderer defaults to Bitstream Vera Sans, which is is not at all metrically compatible with Helvetica. I just switched it to Arial and it's fine now. Fvasconcellos (t·c) 14:53, 18 July 2008 (UTC)

Valued image[edit]

Hi there, I was wondering if you could transform this image to a SVG, so the text could be easily translated to other languages. If that is possible, I think it could be a good valued image candidate. TimVickers (talk) 22:39, 3 September 2008 (UTC)

Yes, embedding is what is what I had in mind, something like this image. I'll drop a note to Sting. Thanks for the pointer! TimVickers (talk) 16:03, 4 September 2008 (UTC)
Its OK, I wasn't at all clear - I can't talk the SVG talk yet! TimVickers (talk) 16:29, 4 September 2008 (UTC)

Image:Molybdopterin.svg[edit]

Oi! Estava a olhar para esta imagem e o meu namorado, que trabalhou um pouco com enzimas contendo molibdopterina, começou a barafustar com a estrutura, rs. Os enxofres ligados ao molibdénio não deveriam estar protonados (quando estão ligados ao metal) e o molibdénio, embora não perfeitamente no plano dos anéis, também não deveria estar atrás do plano, deveria antes formar um anel com os enxofres... Bem, não mates o mensageiro, ele é que se queixou, rsrsrs. De onde the inspiraste para esta estrutura? Não sei se existem diferentes versões. Abraço, Patrícia msg 22:00, 18 September 2008 (UTC)

Ah, confundi os tracejados. Bem, a ligação metal-enxofre pode ser descrita com um traço normal; mesmo sendo um "composto de coordenação", é uma ligação química com tanto direito como as outras, rs. Não acho necessário mudar o nome da imagem, não existe molibdopterina que não seja cofactor, de qualquer modo... Muito obrigada! Patrícia msg 19:44, 22 September 2008 (UTC)
Na verdade, como são, sei lá, cinco ou seis grupos no mundo inteiro que se preocupam sobre o assunto :D, a nomenclatura não está muito definida; o correcto parece chamar o cofactor de "piranopterina" (pyranopterin), pois pode ligar molibdénio ou tungsténio. Só que não há evidência de um metal poder ser trocado pelo outro in vivo (tanto quanto saiba, mas de facto não é a minha especialidade) e tanto quanto me lembro (deveria ter procurado um pouco mas agora deu-me a preguiça :P) há organismos que usam um metal ou o outro. Ou seja, a piranopterina torna-se molibdopterina quando liga um molibdénio e tungstopterina (?) quando liga um tungsténio... não sei se ajudei ou confundi, hehehe. Patrícia msg 22:07, 22 September 2008 (UTC)
Mais uma vez muito obrigada pela nova imagem (fizeste um homem feliz, hahaha). Sim, se encontrar por aí alguma coisa que estranhe, volto a chatear ;). Patrícia msg 19:41, 24 September 2008 (UTC)

Image:Butylscopolamine skeletal.svg[edit]

Hello,

the structure

Butylscopolamine skeletal.svg

of Butylscopolamine is wrong:

I would appreciate a correction of this formula, since it is used in 5 other wikipediae. --131.220.136.195 14:19, 22 September 2008 (UTC)

Here is a link to the correct formula: [1]

Will do. I'm not sure the positions of methyl/butyl should be reversed, though; see e.g. Studies in Natural Products Chemistry and Sigma-Aldrich. Best wishes, Fvasconcellos (t·c) 21:23, 22 September 2008 (UTC)
Well, I consulted a whole lot of schoolbook of medicinal chemistry and also my profs in my pharmaceutical study said that it is the main difference between butylscopolamine and ipratropium or oxitropium. --131.220.136.195 12:00, 23 September 2008 (UTC)
Add-on: please consult the en:European Pharmacopoeia 5 or the en:Merck Index, both of which see the butyl rest equatorial and the gmethyl rest axial. --131.220.136.195 15:19, 23 September 2008 (UTC)
see here...
All right, then. I'll upload a new version shortly. Thanks again for bringing this to my attention! Fvasconcellos (t·c) 16:18, 23 September 2008 (UTC)
BTW: There is an ongoing discussion on the German Wikipedia. --Leyo 18:10, 23 September 2008 (UTC)
Which I cannot take part in—I can't speak a word of German. Google's not much help (I don't think it can cope with the chemistry jargon :) Fvasconcellos (t·c) 20:43, 23 September 2008 (UTC)
OK, an English summary of that comment:
Chemical Abstracts Service says that the CAS number 7182-53-8 has no defined configuration at the nitrogen. The different configurations in books are caused by the fact that the configuration (methyl and butyl group) has to be drawn in some way. Both diastereomeric forms have CAS numbers: the diastereomer in your image 790180-31-3 (bromide: 150521-10-1), the other diastereomer with exchanged butyl and methyl group 768332-46-3 (bromide: 150521-07-6). I venture to doubt that there is only one diastereomeric form present in commercial products.
Did that help? --Leyo 21:03, 23 September 2008 (UTC)
Yes indeed :) Thanks. I've (finally) uploaded the image as requested, though I'm still not so sure it was necessary—hope that helps! Fvasconcellos (t·c) 21:06, 23 September 2008 (UTC)
I think both diastereomeric forms should be shown in the article. --Leyo 23:50, 23 September 2008 (UTC)
I don't, because only one is pharmaceutically relevant. I. e. the one which is listed in the pharmacopoeiae of this world. --131.220.136.195 07:36, 24 September 2008 (UTC)

If you like, I can upload the structure of the other isomer under a different name, say, Image:Butylscopolamine skeletal 2.svg or Image:Butylscopolamine skeletal minor.svg. Fvasconcellos (t·c) 00:04, 27 September 2008 (UTC)
Well, the other structure is just an impurity, not the drug itself. I don't know whether there is any relevance, except you want to mention the impurities in the article. --91.55.122.205 11:28, 28 September 2008 (UTC)
Very often, enantiomeric forms of the same drug may have different potencies, but more importantly, different physiological properties, cf. thalidomide. Compendia very often list stereochemical mixtures for drugs when they are first synthesized and tested. Then, if a new physiological property is discovered for a distinct stereoisomer, a new drug name is dreamed up by marketeers and this name enters the compendia. It is essential to Pharmacology that stereoisomers be listed in the originally named drug. This is not a blind exercise in reductive logic. Laburke (talk) 15:51, 14 May 2011 (UTC)

w:Bortezomib[edit]

Hi, I'm going through our SDF trying to validate some of our chemboxes and drugboxes, and I noticed that Image:Bortezomib.svg appears to be the enantiomer of the title compound, assuming the IUPAC name is correct. Can you check your sources, and find out if the IUPAC name is wrong and your structure is right, or vice versa, then make the necessary adjustments? Thanks, Walkerma (talk) 04:58, 13 October 2008 (UTC)

I just checked in the SDF file provided by CAS, and that also appears to indicate that you've drawn the enantiomer. Can you fix this, unless I made a mistake? Thanks, Walkerma (talk) 05:40, 13 October 2008 (UTC)

Yep, I've just checked as well. One more for the fix-it pile... Thanks for the note! Fvasconcellos (t·c) 12:01, 13 October 2008 (UTC)
...and done. Fvasconcellos (t·c) 13:42, 13 October 2008 (UTC)
Thanks a lot for fixing that. It would be great if you could check a few, take a look at w:Wikipedia:WikiProject Chemicals/Chembox validation and see if you can help. Many of them are drugboxes, so your expert eye would be useful. Also see the talk page for some outstanding issues. If you need the SDF file for the first 500, send an email to me (WalkermaATpotsdamDOTedu). Also, we're meeting on #wikichem tomorrow at 1500h UTC, so please join us then (if you can) to discuss the upload. Many thanks, Walkerma (talk) 06:02, 14 October 2008 (UTC)

New Zealand OFLC Tags[edit]

I just saw you at Patrícia's page and would like to know if you could do some vectorizing in theses tags [3], [4]. If not, there is no problem. Thanks for the attention and good luck with Image:COA Ayuntamiento Cordoba.svg Mizunoryu 大熊猫❤小熊猫 (talk)

They can be used under {{PD-textlogo}} and {{PD-shape}} like theses ones here. But, the logogram in the middle of the labels are bothering me. I'm gonna talk to Patrícia about this and ask for permission too.Mizunoryu 大熊猫❤小熊猫 (talk) 13:14, 14 October 2008 (UTC)

I'm trying to convince OFLC to grant me permission for use their labels, meanwhile you could vectorize these ones [5], [6], [7], [8], [9], [10], [11], [12], [13], [14] Face-devil-grin.svg Mizunoryu 大熊猫❤小熊猫 (talk) 18:24, 15 October 2008 (UTC) I must say that I looked for the best ones, and these were the best ones I could find :( .

Hi Fvasconcellos. A user replaces numerous of SVG structures by his own. Images drawn by you are also involved, e.g. File:Cyclizine.svg or File:Tianeptine.svg. Is this OK for you, including being removed as the author? Some other users do not like it (see sections at the bottom). --Leyo 20:15, 20 January 2009 (UTC)

I'm perfectly fine with it, as long as the new ones are not inaccurate. Most of the structures he's replacing were old ones not up to CSDG standards anyway. If it's no longer my version, I should certainly be removed as the author :) Fvasconcellos (t·c) 12:30, 21 January 2009 (UTC)

New research relevant to clopidogrel (PLAVIX)[edit]

You're a recent contributor/editor for the topic clopidogrel (e.g., PLAVIX ) and I thought you might find the following relevant to that section:

http://www.sciencedaily.com/releases/2009/01/090128113250.htm

"ScienceDaily (Jan. 30, 2009) — Patients taking the common cardiac drug clopidogrel following a heart attack are at a significantly higher risk of a recurrence if they are also taking widely used acid-lowering medications called proton pump inhibitors, a new study has found.

The study, conducted over 6 years in thousands of heart attack patients aged 66 years and older, found a significantly increased risk of readmission for heart attacks if patients were taking one of several proton pump inhibitors, including omeprazole, lansoprazole, or rabeprazole. The investigators found no such association with the proton pump inhibitor pantoprazole or with other acid-lowering medications called H2 receptor antagonists."

I'm totally a wiki user, and not at all conversant with the rules / etiquette of editing/modifying so I'm staying clear....

Susan

Hi Susan. I apologize for taking so long to answer, but I'd somehow missed this message until now. I've actually contributed very little to the clopidogrel article over on Wikipedia, but I'll see about adding this information.

Thanks a lot for contributing to the Wikimedia Commons! Here's a tip to make your uploads more useful: Why not add some categories to describe them? This will help more people to find and use them.

Here's how:

1) If you're using the UploadWizard, you can add categories to each file when you describe it. Just click "more options" for the file and add the categories which make sense:

Uploadwizard-categories.png

2) You can also pick the file from your list of uploads, edit the file description page, and manually add the category code at the end of the page.

[[Category:Category name]]

For example, if you are uploading a diagram showing the orbits of comets, you add the following code:

[[Category:Astronomical diagrams]]
[[Category:Comets]]

This will make the diagram show up in the categories "Astronomical diagrams" and "Comets".

When picking categories, try to choose a specific category ("Astronomical diagrams") over a generic one ("Illustrations"). Pro-tip: The CommonSense tool can help you find the best category for your image.

Thanks again for your uploads! More information about categorization can be found in Commons:Categories, and don't hesitate to leave a note on the help desk.

Increase res[edit]

Hey Fvasconcellos. One question: When I am preparing some protein structures (e. g. this) using Pymol, exporting results only in a moderate res. How to increase the resolution? Cheers, --Yikrazuul (talk) 17:11, 14 July 2009 (UTC)

Ok, I've found the command. BUT - I have problems to get rid of the background. If it's black, someone could critize that. If I don't save transparency (using IrfanView), than I get this. If you zoom in, than you see my problem...What is your advise? Cheers, --Yikrazuul (talk) 17:22, 14 July 2009 (UTC)
I see you found the command to increase the resolution :) Render the image at a very high resolution (like 2000px on the smaller side; this image could be rendered with png 1938,2384 ) and then resize it to 1000px or so in IrfanView or GIMP to fix the aliased edges. Do you know PyMolWiki? There's a lot of information there. Fvasconcellos (t·c) 21:19, 14 July 2009 (UTC)
Nice work, by the way! Fvasconcellos (t·c) 21:19, 14 July 2009 (UTC)

Hi there - your previous Phosphoenolpyruvate image was correct, vice the current one[edit]

I'm not sure how to replace it or I would. In any case, thought you should know. I'm not sure why you changed it, but the previous one is correct. Thanks for all your contributions.

Hi there! What do you mean? There are only 6 oxygen atoms in phosphoenolpyruvate. Best, Fvasconcellos (t·c) 02:56, 19 August 2009 (UTC)


Complex II Diagram[edit]

I believe that your diagram of succinate dehydrogenase (SDH, complex II of the mitochondrial electron transport chain) is inaccurate. The mammalian enzyme does not contain a heme and does not pass its electrons through a heme. There may be some confusion about this because some bacteria have heme b cytochromes that bind SDH to the cell membrane. However, bacteria and mammalian mitochondria are different. RayMosteller, Assoc Prof of Biochemistry & Molecular Biology, USC.

http://commons.wikimedia.org/wiki/File:Complex_II.svg

Hello, Professor, isn't heme present in most SQR complexes? I had no idea that mammalian complex II does not contain a heme group. I'll gladly alter the image if necessary, but as I'm not its author (I only converted it to a vector file format), you should probably contact him: Tim Vickers at the English Wikipedia. Best wishes, Fvasconcellos (t·c) 02:23, 2 September 2009 (UTC)

Clofarabine structure[edit]

Thanks very much for your contributions. I wanted to note that your structure of clofarabine is not quite correct - the 2´-fluoro group should be on the beta face of the ribose ring, consistent with the stereochemistry in arabinose. Thanks!

Thank you for bringing this to my attention. I'll correct it as soon as possible. Fvasconcellos (t·c) 15:49, 30 September 2009 (UTC)
Fixed! Fvasconcellos (t·c) 19:36, 18 October 2009 (UTC)

Error in sarkosyl image[edit]

Hi,

Your rendering of sodium lauroyl sarcosinate is missing an additional carbon on the tail. Lauryl or lauroyl indicates 12 carbons after the carbonyl group. Also, the molecular formula indicates that there are 15 carbons, not 14 as in your image.

I'm sorry, but the image is perfectly accurate; compare it to [15]. There are indeed 15 carbons in the image, not 14 (you can count them again if you like). Best wishes, Fvasconcellos (t·c) 19:36, 18 October 2009 (UTC)

File:Peramivir.svg[edit]

Hello, the fifth stereo center in this formula is missing. PubChem picture is incorrect, see the IUPAC name (1S,2S,3S,4R)-3-[(1S)-1-acetamido-2-ethyl-butyl]-4- (diaminomethylideneamino)-2-hydroxy-cyclopentane- 1-carboxylic acid. Could you please change it? Regards. --Ayacop (talk) 19:10, 29 October 2009 (UTC)

Fixed. Thank you for bringing this to my attention! Fvasconcellos (t·c) 20:55, 30 October 2009 (UTC)

Molybdopterin[edit]

See User talk:Edgar181#Molybdopterin now User talk:Edgar181/Archive2009#Molybdopterin --Leyo 10:42, 22 December 2009 (UTC)

I would like to finally decide whether your two disputed images of molybdopterin should be kept or deleted. Do you agree that they show an incorrect structure? --Leyo 22:42, 21 September 2010 (UTC)

Lactacystin structure[edit]

Hi. In the structure of Lactacystin (http://en.wikipedia.org/wiki/File:Lactacystin.svg) one does not need to explicitly draw the wedge and the hydrogen in the 2-methylpropyl moiety. No stereocenter there. Cheers, Kalju

Thank you for letting me know. I instinctively went back to the source to check—and can't find lactacystin in the article! Best wishes, Fvasconcellos (t·c) 23:39, 5 March 2010 (UTC)

The chemical structure you have uploaded and re-uploaded for radezolid (CAS 869884-78-6) is incorrect. Please check your WHO reference carefully; the C-5 decoration is not an ester but rather an acetamide. You may also consult the following web page: http://www.chemblink.com/products/869884-78-6.htm. Of course, you may also check out the "Publications and Posters" section of the relevant company's website (http://www.rib-x.com) for the structure. Thank you.

Yes, of course. Thank you for noticing. I only uploaded the structure once—what do you mean by reuploaded? Best, Fvasconcellos (t·c) 02:30, 19 March 2010 (UTC)

How to credit you for Substance P space-filling model[edit]

Hello - I would like to use your space-filling Substance P model in a talk I'm giving. How should I credit you? The images I'm using typically receive a "© date & name" next to them.

Hi there! This reply is probably coming too late, but I have released that image into the public domain. No credit is necessary. I hope you were able to use it! Best, Fvasconcellos (t·c) 12:50, 6 May 2010 (UTC)

File:Cystathionine.svg[edit]

Hi Fvasconcellos. Your images has been tagged. Can you please address the dispute? --Leyo 17:10, 17 April 2010 (UTC)

Hi Leyo, I'll see what I can do. I haven't been around much. Fvasconcellos (t·c) 12:50, 6 May 2010 (UTC)
And... done :) Fvasconcellos (t·c) 17:55, 20 June 2010 (UTC)

File:Carnosic acid.svg[edit]

Hi Fvasconcellos, is there a special reason why you drew the bonds to the two methyl groups as triangulars? This suggests a stereogenic center which is not present. I would suggest to keep the formula flat. --Mabschaaf (talk) 17:46, 1 May 2010 (UTC)

Hi there, that was just to imply the true geometry (as the groups are not coplanar), I used to do that in my old structures—before I learned it's usually inappropriate. I'll correct it as soon as I can. Best, Fvasconcellos (t·c) 12:50, 6 May 2010 (UTC)
Hi again... now fixed. I apologize for taking so long to address this. Best, Fvasconcellos (t·c) 17:37, 20 June 2010 (UTC)

ADP-ribose wrong configuration[edit]

Hi. I found a mistake in your structure of ADP-ribose. It's actually a mistake found in several textbooks and research papers. The stereochemical configuration of each of the chiral centres in the left-hand ribose (the one remote from the adenine) is wrong. As shown, this ribose is L-ribose, whereas the one attached directly to the adenine is D-ribose. It would be helpful if you modified it. Thanks.

Error in the structure of Cefaclor[edit]

Hello, I just want to mention that your stucture of structure is not correct: a chiral carbon is missing. Please modify your picture according to this picture. Thank you Snipre (talk) 16:15, 28 May 2010 (UTC)

Fixed, thank you! Best, Fvasconcellos (t·c) 17:31, 20 June 2010 (UTC)

File:Tetrahydrofolic acid.svg[edit]

Hi, in this structural formula is missing the stereochemical information at C-6. Perhaps you could add it? Thanks a lot --Mabschaaf (talk) 18:16, 8 August 2010 (UTC)

IMHO, there are two chiral centers. --Leyo 15:18, 9 August 2010 (UTC)
Yes indeed :) Will upload a new version ASAP. Fvasconcellos (t·c) 01:34, 12 August 2010 (UTC)
Done. Thank you for bringing this to my attention—and thank you, Leyo, for reminding me of the chiral center at the glutamate moiety :) Fvasconcellos (t·c) 00:25, 13 August 2010 (UTC)

Hi Fvasconcellos, this one misses info on a stereo bond, where cyclopropyl binds. Good occasion to say thanks for your work, though. Cheers --Ayacop (talk) 15:42, 8 October 2010 (UTC)

Hi Ayacop, thank you for the compliment! You do some great work yourself :) I'll fix it right away, and update the style while I'm at it. Best, Fvasconcellos (t·c) 18:36, 9 October 2010 (UTC)

Pazufloxacin.svg[edit]

Can you please take a look at File:Pazufloxacin.svg? An oxygen atom appears to be in the wrong position - it should be moved over to the right one place. PubChem. Edgar181 (talk) 16:31, 19 October 2010 (UTC)

Hi Ed—fixed, thank you!
By the way, I see you are uploading SVGs now. Congratulations and welcome to the club :) Fvasconcellos (t·c) 23:41, 20 October 2010 (UTC)
I now have the version of ChemDraw that can export SVGs, and User:Smallman12q created a script for me to create a transparent background, and I figured out how to use InkScape to add margins as Leyo suggested. So all the pieces have been put together.  :) Edgar181 (talk) 14:44, 21 October 2010 (UTC)

Hi Fvasconcellos. I tagged your file as disputed. You may want to fix it. --Leyo 19:31, 14 April 2011 (UTC)

Hello, the articles de:Queuin and en:Queuine have new images. As the old structure is incorrect, it would be the best to delete it. With kind regards --JWBE (talk) 18:52, 16 April 2011 (UTC)

H-bonding[edit]

After all your fine work, I hate to be a bearer of bad news. If you want to portray the lowest energy conformation of any of your amino acids, such as gabapentin, you need to account for the hydrogen bonding between the hydrogen on the carboxylic acid and the lone pair on the amine. A quick calculation on the DFT optimized structures (B3LYP//6-31G*) showed that the H-bonded structure is 8 kcal/mol (33.5 kJ/mol) lower than the your free amine conformation. Laburke (talk) 19:06, 14 May 2011 (UTC)

Hi there. Not bad news at all—as one of my oldest models, that one was created without any sort of optimization; I am fully aware of its relative "inaccuracy" :) Please feel free to replace it with an optimized model you may have created. Thank you for bringing this to my attention, and best wishes! Fvasconcellos (t·c) 22:20, 20 May 2011 (UTC)

File:1,1,2-Trichloro-1,2,2-trifluoroethane skeletal.svg[edit]

Hi Fvasconcellos, I recognized that in the structure above the height of the "L"s is a little bit bigger than the height of the "C"s. This may cause some trouble if the "L"s are misinterpreted as lone pairs. Could you please fix that? Thx --Mabschaaf (talk) 17:53, 19 June 2011 (UTC)

Sure. I've edited the file, that ought to do it. Please purge your cache if the change isn't showing yet. Best wishes, Fvasconcellos (t·c) 18:01, 19 June 2011 (UTC)

Confusing perspective of Cisapride diagrams[edit]

The diagrams of cisapride appear confusing and perhaps wrong stereochemistry. My major concern is difficulty in visualizing the piperidine ring geometries. File:Cisapride.svg has the wedged part up, opposite of usual chair perspective (front of chair down), and that makes the stereochemistry of the methoxy group R where the en.wp article says it's S. The 3D form File:Cisapride 3D.png could benefit from a slight tilt of that ring so the connectivities can be seen more clearly (and to confirm what the intended stereochemistry actually is at methoxy). DMacks (talk) 16:47, 21 July 2011 (UTC)

Source[edit]

Hi!

Congrats on your many excellent pictures! Regarding the Mitochondrial_electron_transport_chain—Etc4.svg, I would like to use it in my thesis. Therefore I have two short questions: a) should I put you or Timothy Vickers as the source since I understand you used his drawing and vectorized it? b) if you are the author to be mentioned, can I use your full name as the form (for Karolinska Institutet) is recommended? You can mail me at reklam@narkos.se if you don´t want to put it down officially ;-) If possible, please answer as soon as you can. Printer´s waiting ...... Take care! -Karsten

Oh dear, I am so sorry for not getting back to you sooner. If there's still time, credit should certainly go to Dr Tim Vickers (you may contact him through User talk:TimVickers). Best wishes and my apologies, Fvasconcellos (t·c) 20:47, 27 August 2011 (UTC)

Stereochemistry of File:Orlistat 3D sticks.png[edit]

The attachment of the N of the formamide to the carbon next to the side-chain ester carbonyl appears to have the wrong stereochemistry. As drawn, the N is behind that C, making the stereocenter R. That contradicts File:Orlistat.svg, which has the N wedged to be S. That latter also agrees with the pubchem and drugbank entries. Could you fix this? DMacks (talk) 16:15, 3 September 2011 (UTC)

I'll see what I can do. I now avoid creating 3D models unless I can get crystallographic data to back them up :| Fvasconcellos (t·c) 17:37, 3 September 2011 (UTC)
Thanks! (geometry without lit-support is one of my pet peeves too:) DMacks (talk) 17:48, 3 September 2011 (UTC)
File:2PX6 orlistat.png is xray of it bound to receptor (sadly no cite to a public dataset). DMacks (talk) 18:46, 3 September 2011 (UTC)

Norfolk Coat of Arms[edit]

Hi there

I am a complete novice at all this, but is it possible to use your brilliant illustration of the Norfolk Coat of Arms on the front cover of a book I am publishing? I would be grateful if you could let me know of any copyright issues I need to take into account. The book will be published in the UK only.

Michelle Tilling

Yes, of course! There are no copyright restrictions—I release all files I create to the public domain. There might be legal restrictions on using the arms themselves; you'd have to check with the council, but I don't think it should be a problem. Best regards, Fvasconcellos (t·c) 13:54, 12 September 2011 (UTC)

How wonderful - thanks! Can I credit you in any way, or send you a free copy of the book when it comes out? My email is [redacted]

Hi, Michelle, you need not credit me in any way. My work was purely "mechanical" as a rendering of the blazon based on an example image.
As for a free copy of the book—sure, I'd love to get one! I'll send an email your way. Best, Fvasconcellos (t·c) 14:22, 12 September 2011 (UTC)


Cisapride[edit]

Hi Fvasconcellos, the structure in file:cisapride.svg is not correct. The methoxy and the acylamino group are connected cis (see "cis-apride") to the piperidine ring. --FK1954 (talk) 19:29, 12 September 2011 (UTC)

Hi there! I see this isn't the first time I've had a complaint about this structure—and I haven't done anything about it! :( I've uploaded a new version. Thank you so much for bringing this to my attention. Best, Fvasconcellos (t·c) 14:43, 13 September 2011 (UTC)

File:Monoamine oxidase A 2BXS.png[edit]

Hello, are the two horizontal lines supposed to be on the image or not? It looks confusing and we got an error report about it on pl.wiki so I'm not sure if that's an artifact or membrane or something.Plushy (talk) 14:07, 29 February 2012 (UTC)

Hi there. Yes, that's supposed to be a mitochondrial membrane (as the image description says, "...oriented as if attached to the outer membrane of a mitochondrion.") Best, Fvasconcellos (t·c) 14:31, 29 February 2012 (UTC)

File:Mitochondrial electron transport chain—Etc4.svg[edit]

There is a typo in the File:Mitochondrial electron transport chain—Etc4.svg image. On Complex I, the proton should be by NADH, not NAD+, so the arrow should show NADH + H+ -> NAD+.

Also, it would be good to reinforce that ADP + Pi goes to ATP + H2O, not just ATP.

Great image!

File:IUPAC-alkane-4.svg[edit]

Can you help? AlanM1 (talk) 11:29, 15 April 2012 (UTC)

Wikipedia's SVG rendering bug strikes for the N+1'th time:( Last I heard, the only robust solution is to convert all the text to paths. Second best (assuming even with font-substitutions the characters stay approximately same size) is to have each separately-styled section of text as a separate item (rather than italicizing a substring within a single non-italic item). Note that this is same same single issue underlying all the reports in the preceding sections as well (seems a lot of effort went into making each one's separate talk-page commentary too!)

dihydrofolic acid structure error?[edit]

http://en.wikipedia.org/wiki/Dihydrofolic_acid shows a thickened triangle between the left two rings and the carbon. My understanding of chemistry is that this means the bond comes out of the page. However, there is a double bond next to the triangle which means it should be flat. I suspect that someone copied the figure from http://en.wikipedia.org/wiki/Tetrahydrofolic_acid where it makes sense.

Substance P space fill model[edit]

Hi Fvasconcellos, I was wondering how did you get the structure information for substance p for your model? Is it from a modeling result, experimental result?

Hi there. Sorry to disappoint you, but... I have no idea! It's been over 6 years since I created that model, and I can't remember. (I do recall it was one of my earliest models, so probably not experimental data or anything of the sort.) I wouldn't vouch for its accuracy, particularly regarding the conformation. Best, Fvasconcellos (t·c) 22:29, 23 January 2013 (UTC)

Your input at Commons:Deletion requests/Bafetinib chemical structures would be appreciated. Thank you. Ed (Edgar181) 16:19, 12 March 2013 (UTC)

I've had a look at the literature and it appears the structure deposited with PubChem and WHO was indeed wrong. Might be time to list File:Bafetinib 2D skeletal.svg for deletion instead. Fvasconcellos (t·c) 18:41, 12 March 2013 (UTC)

Haworth projection[edit]

I have marked a couple of your images with the chemistry quality template because they are Haworth projections that do not use the standard conventions for indicating stereochemistry. Do you think you could update them? Thank you, ChemNerd (talk) 20:41, 26 March 2013 (UTC)

Sorry to trouble you, but here are a couple more File:Aminoimidazole carboxamide ribonucleotide.svg ✓ Done, File:Aminoimidazole ribotide.svg ✓ Done, File:Adenosine diphosphate ribose.svg ✓ Done ... and probably others. ChemNerd (talk) 20:48, 26 March 2013 (UTC)
Thanks for letting me know. I'll have a look at these over the weekend. Best, Fvasconcellos (t·c) 02:34, 29 March 2013 (UTC)
Thank you. ChemNerd (talk) 13:39, 29 March 2013 (UTC)
That's nearly all of them done. I'll probably make a Mills version of adenylosuccinate, because the conformation is impossible to represent accurately with a Haworth projection. Fvasconcellos (t·c) 20:32, 30 March 2013 (UTC)

Issue with "citrulination" figure[edit]

Hello, First, thanks for all your contributions. That said, your citrulination figure has an issue. Since the page discusses a post-translational modification of arginine residues in proteins, the structure should be of a peptide. As it is, there is an extra oxygen in the truncated backbone. The backbone, of course, goes N1-Calpha-Ccarbonyl-N2. (amine--alpha carbon--carbonyl carbon--amine of the next residue). You have included the oxygen from the carboxyl, which is lost during peptide bond formation. I would fix it with a correct structure, but I cannot overwrite the file. Thanks -tony

I converted the O to N in the backbone. However, given the placement of the wiggly-lines, is there too much of the backbone included (suggests that N of one reside links to a *different* N on the next)? DMacks (talk) 11:21, 2 June 2013 (UTC)

File:Luminol chemiluminescence molecular representation.svg[edit]

There appears to be an error in one of the chemical structures in this image, as pointed out by another editor. (I moved a comment from the enwiki article to the image talk page here). Regards, Ed (Edgar181) 14:32, 12 May 2013 (UTC)

Jesus, it's been 6 months to get to this. I am so sorry, Ed—I'll edit and upload a new version right away. Best, Fvasconcellos (t·c) 18:58, 8 November 2013 (UTC)

Antibody.svg is confusing.[edit]

Thanks for your contributions to wiki. I was finding the picture of how the antibody binds to the antigen confusing because it shows that the "key" is always symmetrical. I was having a hard time understanding how the heavy and light chains could matchup and create a symmetrical key. I asked a Ph.D. from UC Berkeley and she said that there is no symmetry and that the picture was probably drawn that way for simplicity. I checked another text and it does not show the symmetry. If you ever update the figure it would be helpful for novice people like myself if it a bit more accurate. Thanks.

Just found a carbon with five bonds in this image in the Triplet Dianion structure. The bond to the negative oxygen should be a single bond instead of a double bond. Hope that helps! —Preceding unsigned comment was added by 171.65.249.4 (talk) 23:48, 31 October 2013‎ (UTC)

Thank you for bringing this to my attention. I'll upload a corrected version of the structure right away. Best wishes, Fvasconcellos (t·c) 19:00, 8 November 2013 (UTC)

Hello Fvasconcellos, for discussions issues I have created this. If you don't mind I would upload my image over yours in order to adress the stereo issue. What do you think? --Yikrazuul (talk) 14:10, 15 June 2014 (UTC)
Hey! Feel free to upload over my file and update the relevant information. Best, Fvasconcellos (t·c) 14:36, 15 June 2014 (UTC)
