Metabolite Identification
Common Name24-Methylcholesterol
DescriptionDihydrobrassicasterol, also known as 24-methylcholesterol, belongs to the class of organic compounds known as ergosterols and derivatives. These are steroids containing ergosta-5,7,22-trien-3beta-ol or a derivative thereof, which is based on the 3beta-hydroxylated ergostane skeleton. Based on a literature review a significant number of articles have been published on Dihydrobrassicasterol. This compound has been identified in human blood as reported by (PMID: 31557052 ). 24-methylcholesterol is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 24-Methylcholesterol 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.
