15-SAHSA, a branched fatty acid ester of hydroxy fatty acids (FAHFAs), is recognized for its involvement in metabolic regulation. This compound comprises stearic acid esterified to 5-hydroxy stearic acid and is notably influenced by dietary changes, such as fasting and high-fat consumption, with a link to insulin sensitivity. SAHSA levels are specifically found to be moderately increased in the serum of AG4OX mice, which are characterized by their glucose tolerance through the overexpression of the Glut4 glucose transporter in adipose tissue. Given the established functions of FAHFAs in enhancing glucose tolerance, prompting insulin secretion, and exerting anti-inflammatory properties, 5-SAHSA emerges as a potential bioactive lipid implicated in the management of metabolic syndrome and inflammation.

Branched fatty acid esters of hydroxy fatty acids (FAHFAs) are lipids influenced by dietary changes, playing a crucial role in insulin sensitivity. These compounds typically consist of a C-16 or C-18 fatty acid (for example, palmitoleic, palmitic, oleic, or stearic acid) linked to a hydroxy fatty acid with the same carbon chain length. 13-PAHSA, a derivative where palmitic acid is esterified to 13-hydroxy stearic acid, is notably prevalent in the adipose tissue of glucose-tolerant AG4OX mice, which exhibit enhanced glucose transport via the overexpression of the Glut4 glucose transporter. This observation, along with the metabolic benefits seen from other FAHFAs—including improved glucose tolerance, stimulated insulin secretion, and anti-inflammatory properties—suggests that 13-PAHSA may function as a bioactive lipid beneficial in managing metabolic syndrome and inflammation.
