Deutsch: Spurenamine (engl. trace amines) sind biogene Amine, die durch Decarboxylierung von Aminosäuren entstehen. Ihrem Namen entsprechend kommen sie im Körper nur in geringen Mengen vor. Ursprünglich wurde angenommen, dass sie ein Abfallprodukt bei der Synthese der Neurotransmitter Dopamin, Serotonin und Noradrenalin seien. Per Zufall jedoch entdeckte Beth Borowsky im Jahr 2001 eine neue Familie von Rezeptoren, die durch Spurenamine spezifisch stimuliert wurden. Sie taufte diese Rezeptoren TA1, TA3, TA4 und TA5. Weitere Rezeptortypen wurden bei Maus und Ratte gefunden. (→Spurenamine)
English: Trace amines are an endogenous group of amines structurally and metabolically related to classical monoamine neurotransmitters, such as dopamine, norepinephrine, and serotonin. Compared to the classical monoamines, they are present in trace concentrations. They are distributed heterogeneously throughout the mammalian brain and peripheral nervous tissues and exhibit high rates of metabolism. Although, they can be synthesized within parent monoamine neurotransmitter systems, there is evidence that suggests that some of them may comprise their own independent neurotransmitter systems.

Português: Aminas traço são compostos endógenos realcionados estruturalmente a aminas biogênicas clássicas, tais como catecolaminas, serotonina e histamina. Como estão presentes em baixas quantidades endógenas, são denominadas aminas traço. Aminas traço incluem p-tiramina, β-feniletilamina, triptamina, octopamina, e 3-iodotironamina, e são encontradas nos sistemas nervosos de animais, de insetos a mamíferos. (→Amina traço)
Српски / srpski: Trag amini su endogena jedinjenja strukturno slična klasičnim biogenim aminima, kao što su kateholamini, serotonin i histamin. U trag amine se uvrstavaju p-tiramin, β-feniletilamin, triptamin, oktopamin, i 3-iodotironamin. Oni su rasprostranjeni u životinjskim nervnim sistemima od insekata do sisara. (→Trag amin)
中文：痕量胺（Trace amine）是一类与经典的 生物胺（如儿茶酚胺类、血清素、组胺）结构类似的内源性物质，包括p-酪胺、β-苯乙胺、色胺、章胺和3-碘类甲腺质，存在于动物（昆虫至哺乳动物）的神经系统中。 (→痕量胺)
