Metabolite Identification
Common NameCholest-5-en-3-ol (3beta)-, (9Z)-9-octadecenoate
Description303-43-5 belongs to the class of organic compounds known as cholesteryl esters. Cholesteryl esters are compounds containing an esterified cholestane moiety. 303-43-5 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 ). Cholest-5-en-3-ol (3beta)-, (9z)-9-octadecenoate is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Cholest-5-en-3-ol (3beta)-, (9Z)-9-octadecenoate 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.
