Metabolite Identification
Common Name20-Hydroxypregn-4-en-3-one
Description20.alpha.-Progerol belongs to the class of organic compounds known as gluco/mineralocorticoids, progestogins and derivatives. These are steroids with a structure based on a hydroxylated prostane moiety. 20.alpha.-Progerol is an extremely weak basic (essentially neutral) compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). 20-hydroxypregn-4-en-3-one is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 20-Hydroxypregn-4-en-3-one 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.
