Metabolite Identification
Common Name7-Keto-dehydroepiandrosterone
Description3-hydroxy-10,13-dimethyl-2,3,4,8,9,11,12,14,15,16-decahydro-1H-cyclopenta[a]phenanthrene-7,17-dione belongs to the class of organic compounds known as androgens and derivatives. These are 3-hydroxylated C19 steroid hormones. They are known to favor the development of masculine characteristics. They also show profound effects on scalp and body hair in humans. 3-hydroxy-10,13-dimethyl-2,3,4,8,9,11,12,14,15,16-decahydro-1H-cyclopenta[a]phenanthrene-7,17-dione 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 ). 7-keto-dehydroepiandrosterone is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 7-Keto-dehydroepiandrosterone 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.
