| Common Name | alpha-Methyltryptamine |
|---|
| Description | alpha-Methyltryptamine, also known as 3-(2-aminopropyl)indole or indopan, belongs to the class of organic compounds known as 3-alkylindoles. 3-alkylindoles are compounds containing an indole moiety that carries an alkyl chain at the 3-position. Based on a literature review very few articles have been published on alpha-Methyltryptamine. This compound has been identified in human blood as reported by (PMID: 31557052 ). Alpha-methyltryptamine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically alpha-Methyltryptamine 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. |
