Metabolite Identification
Common Name3,5-Cholestadien-7-one
DescriptionCHOLESTA-3,5-DIEN-7-ONE belongs to the class of organic compounds known as cholestane steroids. These are steroids with a structure containing the 27-carbon cholestane skeleton. CHOLESTA-3,5-DIEN-7-ONE 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 ). 3,5-cholestadien-7-one is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 3,5-Cholestadien-7-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.
