<p>Palmitoleic acid, an ω-7 monounsaturated fatty acid found in macadamia and sea buckthorn oils, enhances both basal and insulin-stimulated glucose uptake, as well as Glut4 protein levels in 3T3-L1 adipocytes at a 200 µM concentration. Ex vivo, at a dosage of 300 mg/kg per day, it significantly increases glucose uptake and both aerobic and anaerobic glycolysis, while decreasing de novo fatty acid synthesis and the activity of lipogenic enzymes, specifically ATP citrate lyase (ACL) and glucose-6-phosphate dehydrogenase (G6PDH), in isolated murine adipocytes. Furthermore, the dietary administration of palmitoleic acid at 300 mg/kg mitigates high-fat diet-induced insulin resistance and liver inflammation in mice.</p>

<p>Branched fatty acid esters of hydroxy fatty acids (FAHFAs) are recent discoveries in endogenous lipids that are influenced by dietary changes such as fasting and high-fat diets, showing a link with enhanced insulin sensitivity in mice. These compounds typically feature a C-16 or C-18 fatty acid (e.g., palmitoleic, palmitic, oleic, or stearic acid) bound to a hydroxy group on another C-16 or C-18 fatty chain. A specific FAHFA, 9-POHSA, consists of palmitoleic acid connected at the hydroxy stearic acid's 9th position. This molecule, in particular, exhibits notably increased levels in the serum of glucose-tolerant AG4OX mice, which express the Glut4 glucose transporter predominantly in their adipose tissue. Given the broader family of FAHFAs' roles in enhancing glucose tolerance, promoting insulin secretion, and exerting anti-inflammatory effects, 9-POHSA emerges as a potential bioactive lipid involved in managing metabolic syndrome and inflammation.</p>
