Metabolite Identification
Common NameEicosadienoic acid
DescriptionEicosadienoic acid is an omega-6 fatty acid found in human milk (PMID: 15256803 ). Omega-6 fatty acids are a family of unsaturated fatty acids which have in common a carbon-carbon double bond in the n−6 position; that is, the sixth bond from the end of the fatty acid. The biological effects of the omega−6 fatty acids are largely mediated by their conversion to n-6 eicosanoids that bind to diverse receptors found in every tissue of the body. Eicosadienoic acid has been identified in the human placenta (PMID: 32033212 ).
