Metabolite Identification
Common NameSterculic acid
DescriptionSterculic acid, also known as 9,10-MT 9C-18:1 or sterculia-saeure, belongs to the class of organic compounds known as medium-chain fatty acids. These are fatty acids with an aliphatic tail that contains between 4 and 12 carbon atoms. Based on a literature review a significant number of articles have been published on Sterculic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). Sterculic acid is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Sterculic 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.
