Metabolite Identification
Common Name5alpha-Pregnane
Description5b-Pregnanediol, also known as a C21-steroid, belongs to the class of organic compounds known as pregnane steroids. These are steroids with a structure based on the 21-carbon pregnane skeleton. Based on a literature review very few articles have been published on 5b-Pregnanediol. This compound has been identified in human blood as reported by (PMID: 31557052 ). 5alpha-pregnane is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 5alpha-Pregnane 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.
