Metabolite Identification
Common Name9Z,12E-Octadecadienoic acid
Description9Z,12E-Octadecadienoic acid, also known as linoelaidic acid or 9Z,12E-octadecadienoate, belongs to the class of organic compounds known as lineolic acids and derivatives. These are derivatives of lineolic acid. Lineolic acid is a polyunsaturated omega-6 18 carbon long fatty acid, with two CC double bonds at the 9- and 12-positions. Based on a literature review a significant number of articles have been published on 9Z,12E-Octadecadienoic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). 9z,12e-octadecadienoic acid is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 9Z,12E-Octadecadienoic 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.
