Metabolite Identification
Common Name22-Oxocholesterol
Description2-{5-hydroxy-2,15-dimethyltetracyclo[8.7.0.0²,⁷.0¹¹,¹⁵]heptadec-7-en-14-yl}-6-methylheptan-3-one belongs to the class of organic compounds known as monohydroxy bile acids, alcohols and derivatives. These are bile acids, alcohols or any of their derivatives bearing a hydroxyl group. Based on a literature review very few articles have been published on 2-{5-hydroxy-2,15-dimethyltetracyclo[8.7.0.0²,⁷.0¹¹,¹⁵]heptadec-7-en-14-yl}-6-methylheptan-3-one. This compound has been identified in human blood as reported by (PMID: 31557052 ). 22-oxocholesterol is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 22-Oxocholesterol 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.
