The structures for asparagine and aspartic acid and respectively glutamine and glutamic acid are wrong.
Image of AAs
[编辑]The amine and carboxylic acid functional groups of the AAs' backbone should be shown as charged also.

The unprotonated nitrogen (no H) of Histidine should be the one with the pKa label. See corrected image. --CorbanSwain (留言) 02:18, 20 September 2014 (UTC)
Specific Amino Acid Comments
[编辑]The tyrosine has polar but uncharged side chains (hydrophilic).--Ytx21cn (留言) 06:36, 12 September 2014 (UTC)
- I'm not a chemist so have no idea what you're talking about, but if you tell me what is required from a visual/graphical point of view I'll make any necessary changes. --Fred the Oyster (留言) 10:13, 12 September 2014 (UTC)
- He is saying the Amino Acid labeled Tyrosine should be grouped under polar (which is kind of true). I would make a new group and call Phenylalanine, Tyrosine and Tryptophan "Amino Acids with Aromatic Side Chains." I would also be inclined to draw Glycine with the --H explicitly. I would also label section A and its title as "Acidic" (now labeled negative) and "Basic" (not labeled positive) and the title could be "Amino Acids with Acidic or Basic Side Chains."--CorbanSwain (留言) 02:30, 20 September 2014 (UTC)
Also, as a previous user mentioned, Glutamic Acid and Aspartic Acid they are labeled should bear the names "Glutamate" and "Aspartate" (since they are in the charged forms), respectively. --CorbanSwain (留言)
wide-screen version
[编辑]If anyone cares, I made a wide-screen version of this excellent graphic.
