Metabolite Identification

Common Name

alpha-Methyl-5-hydroxytryptamine; alpha-Methylserotonin

Description

alpha-Methyl-5-hydroxytryptamine; alpha-Methylserotonin, also known as alpha-methyl-5-HT or alpha-methyl-5-hydroxytryptamine, belongs to the class of organic compounds known as serotonins. Serotonins are compounds containing a serotonin moiety, which consists of an indole that bears an aminoethyl a position 2 and a hydroxyl group at position 5. Based on a literature review a significant number of articles have been published on alpha-Methyl-5-hydroxytryptamine; alpha-Methylserotonin. This compound has been identified in human blood as reported by (PMID: 31557052 ). Alpha-methyl-5-hydroxytryptamine; alpha-methylserotonin is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically alpha-Methyl-5-hydroxytryptamine; alpha-Methylserotonin 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.
