Metabolite Identification
Common NameHomocastasterone
DescriptionHomocastasterone belongs to the class of organic compounds known as stigmastanes and derivatives. These are sterol lipids with a structure based on the stigmastane skeleton, which consists of a cholestane moiety bearing an ethyl group at the carbon atom C24. Based on a literature review a significant number of articles have been published on Homocastasterone. This compound has been identified in human blood as reported by (PMID: 31557052 ). Homocastasterone is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Homocastasterone 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.
