Metabolite Identification
Common NameEpi-Friedelanol
Description4,4a,6b,8a,11,11,12b,14a-octamethyl-docosahydropicen-3-ol 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 4,4a,6b,8a,11,11,12b,14a-octamethyl-docosahydropicen-3-ol. This compound has been identified in human blood as reported by (PMID: 31557052 ). Epi-friedelanol is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Epi-Friedelanol 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.
