13-SAHSA

13-SAHSA, a branched fatty acid ester of hydroxy fatty acids (FAHFAs), has been found to be involved in metabolic regulation, particularly in relation to fasting, high-fat feeding, and insulin sensitivity. This compound is a synthesis of stearic acid and 13-hydroxy stearic acid. Notably, 13-SAHSA levels are found to be moderately increased in the serum of AG4OX mice, which are characterized by their glucose tolerance and expression of the Glut4 glucose transporter specifically in their adipose tissue. Similar to other FAHFAs, 13-SAHSA is believed to play a significant role in enhancing glucose tolerance, stimulating insulin secretion, and exerting anti-inflammatory effects, indicating its potential importance in addressing conditions related to metabolic syndrome and inflammation.
