Abstract

Fatty acid esters of hydroxy fatty acids (FAHFAs) have been identified as a novel class of bioactive lipids with beneficial effects on insulin secretion, glucose metabolism and metabolic inflammation. Palmitic acidhydroxystearic acids (PAHSAs), a subgroup of FAHFAs, are reduced in serum and fat of insulin resistant mice and humans. A recent paper
