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(16:1(9Z)/5-O-16:0), in particular, is formed from the condensation of the carboxy group of palmitoleic acid with the hydroxy group of 5-hydroxyhexadecanoic acid. It is alternatively named 5-POHPA since it is the 5-hydroxy isomer of the POHPA (palmitoleic acid-hydroxypalmitic acid) family.
