Metabolite Identification
Common Name17-Hydroxylinolenic acid
Description17-Hydroxylinolenic acid is a hydroxylated (on the 17th carbon) version of alpha linolenic acid produced from alpha linolenic acid. Another isomer known as 2-hydroxylinolenic acid is also known to exist. Alpha-Linolenic acid is an organic compound found in many common vegetable oils. Systematically, it is named all-cis-9,12,15-octadecatrienoic acid (PMID:11413487 ). In physiological literature, it is given the name 18:3 (n−3). Alpha-linolenic acid is a carboxylic acid with an 18-carbon chain and three cis double bonds. The first double bond is located at the third carbon from the n end. Thus, α-linolenic acid is a polyunsaturated n−3 (omega-3) fatty acid. It is an isomer of γ-linolenic acid, a polyunsaturated n−6 (omega-6) fatty acid (PMID: 19269799 ).
