Metabolite Identification

Common Name

5-Aminoindole

Description

5-Aminoindole, also known as indol-5-ylamine, belongs to the class of organic compounds known as indoles. Indoles are compounds containing an indole moiety, which consists of pyrrole ring fused to benzene to form 2,3-benzopyrrole. Based on a literature review a significant number of articles have been published on 5-Aminoindole. This compound has been identified in human blood as reported by (PMID: 31557052 ). 5-aminoindole is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 5-Aminoindole is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
