Description | Branched 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(16:0/7-O-18:0), in particular, is formed from the condensation of the carboxy group of palmitic acid with the hydroxy group of 7-hydroxyoctadecanoic acid. It is alternatively named 7-PAHSA since it is the 7-hydroxy isomer of the PAHSA (palmitic acid-hydroxystearic acid) family. |
