Notes: 5-PAHSA-d31 is intended for use as an internal standard for the quantification of 5-PAHSA (Item No. 17043) by GC- or LC-MS. Branched fatty acid esters of hydroxy fatty acids (FAHFAs) are newly identified endogenous lipids regulated by fasting and high-fat feeding and associated with insulin sensitivity.{27644} 5-PAHSA is a FAHFA in which palmitic acid is esterified at the 5th carbon of hydroxy stearic acid. PAHSA isoforms are the most abundant forms of FAHFA identified in the adipose tissue of glucose tolerant AG4OX mice.{27644} PAHSAs are synthesized in vivo in both mice and humans and are regulated by fasting and high-fat feeding in mice.{27644} PAHSA levels correlate highly with insulin sensitivity and are reduced in adipose tissue and serum of insulin-resistant humans. PAHSA administration lowers ambient glycemia, improves glucose tolerance, and stimulates GLP-1 and insulin secretion in mice.{27644}
