Metabolite Identification
Common Namealpha-Amyrin
Descriptionalpha-Amyrin, also known as a-amyrin, belongs to the class of organic compounds known as triterpenoids. These are terpene molecules containing six isoprene units. Based on a literature review very few articles have been published on alpha-Amyrin. This compound has been identified in human blood as reported by (PMID: 31557052 ). Alpha-amyrin is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically alpha-Amyrin 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.
