General description

Palmitic acid and hydroxystearic acid (PAHSA) containing (O-acyl)-hydroxy fatty acids are being found in tissues and serum extracts of mouse and human.

Application

5-PAHSA or 5-(palmitoyloxy)octadecanoic acid might be used as (O-acyl)-hydroxy fatty acids (OAHFAs) standard to determine ester position in isomeric OAHFAs by ion trap mass spectrometry. It is also suitable for use as a standard for the quantification of fatty acid esters of hydroxy fatty acids (FAHFAs) by liquid chromatography–mass spectrometry (LC-MS).

Biochem/physiol Actions

Palmitic acid and hydroxystearic acid (PAHSA) levels correlate highly with insulin sensitivity and are reduced in adipose tissue and serum of insulin-resistant humans. In adipocytes, PAHSAs signal through G-protein-coupled receptor 120 (GPR120) to enhance insulin-stimulated glucose uptake. PAHSAs are fatty acid esters of hydroxy fatty acids (FAHFAs), which are endogenous lipids with the potential to treat diabetes and inflammation.
