Common NameFAHFA(22:6(4Z,7Z,10Z,13Z,16Z,19Z)/9-O-18:2(10E,12Z))
DescriptionBranched fatty acid esters of hydroxy fatty acids (FAHFAs) are endogenous lipids found in adipose tissue and serum that correlate with insulin sensitivity and are reduced in insulin-resistant humans. Structurally, they are characterized by a branched ester linkage between a fatty acid and a hydroxy-fatty acid. Different positions of the branched ester on the hydroxy fatty acid results in different isomers. FAHFA(22:6(4Z,7Z,10Z,13Z,16Z,19Z)/9-O-18:2(10E,12Z)), in particular, is formed from the condensation of the carboxy group of docosahexaenoic acid (DHA) with the hydroxy group of 9-hydroxyoctadecadienoic acid. It is alternatively named 9-DHAHLA since it is the 9-hydroxy isomer of the DHAHLA (docosahexaenoic acid-hydroxylinoleic acid) family.
