Metabolite Identification
Common Name24,25-Epoxycholesterol
Description14-[4-(3,3-dimethyloxiran-2-yl)butan-2-yl]-2,15-dimethyltetracyclo[8.7.0.0²,⁷.0¹¹,¹⁵]heptadec-7-en-5-ol belongs to the class of organic compounds known as cholesterols and derivatives. Cholesterols and derivatives are compounds containing a 3-hydroxylated cholestane core. 14-[4-(3,3-dimethyloxiran-2-yl)butan-2-yl]-2,15-dimethyltetracyclo[8.7.0.0²,⁷.0¹¹,¹⁵]heptadec-7-en-5-ol 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 ). 24,25-epoxycholesterol is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 24,25-Epoxycholesterol 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.
