| Common Name | (22S)-22-Hydroxycholesterol |
|---|
| Description | (22S)-22-Hydroxycholesterol, also known as cholest-5-ene-3beta,22-diol or 22(R)OH cholesterol, belongs to the class of organic compounds known as dihydroxy bile acids, alcohols and derivatives. Dihydroxy bile acids, alcohols and derivatives are compounds containing or derived from a bile acid or alcohol, and which bears exactly two carboxylic acid groups. Based on a literature review very few articles have been published on (22S)-22-Hydroxycholesterol. This compound has been identified in human blood as reported by (PMID: 31557052 ). (22s)-22-hydroxycholesterol is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically (22S)-22-Hydroxycholesterol 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. |
