Metabolite Identification
Common Name24-Nor Ursodeoxycholic Acid
Description24-Nor Ursodeoxycholic Acid, also known as 24-nor ursodeoxycholate, 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 a significant number of articles have been published on 24-Nor Ursodeoxycholic Acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). 24-nor ursodeoxycholic acid is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 24-Nor Ursodeoxycholic Acid 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.
