Common NameFAHFA(18:1(9Z)/10-O-18:0)
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(18:1(9Z)/10-O-18:0), in particular, is formed from the condensation of the carboxy group of oleic acid with the hydroxy group of 10-hydroxyoctadecanoic acid. It is alternatively named 10-OAHSA since it is the 10-hydroxy isomer of the OAHSA (oleic acid-hydroxystearic acid) family.
