Palmitoleic Acid

Palmitoleic Acid (CAS No.: 373-49-9) is a naturally occurring ω-7 monounsaturated long-chain fatty acid widely found in lipid-rich botanical sources such as macadamia and sea buckthorn oils, and is classified within the broader family of bioactive fatty acids implicated in metabolic regulation. In biomedical research, it is recognized for its role as a lipid signaling molecule that modulates glucose and lipid metabolism, partly through enhancing glucose uptake and upregulating glucose transporter 4 (GLUT4) expression in adipocytes, as well as influencing key metabolic pathways associated with glycolysis and lipogenesis. Experimental evidence indicates that palmitoleic acid can increase both aerobic and anaerobic glucose utilization while suppressing de novo fatty acid synthesis through downregulation of enzymes such as ATP citrate lyase and glucose-6-phosphate dehydrogenase, suggesting a coordinated effect on cellular energy homeostasis. Its activity is typically observed in the low micromolar to mid micromolar range in vitro, depending on the cellular context, and it has been employed in adipocyte and metabolic disease models to investigate insulin sensitivity, lipid metabolism, and inflammatory responses. In vivo studies further support its potential to ameliorate diet-induced insulin resistance and hepatic inflammation, as well as its association with protective effects in models of cerebrovascular dysfunction. As such, palmitoleic acid is frequently utilized in studies exploring metabolic disorders, lipid signaling pathways, and therapeutic strategies targeting cardiometabolic and inflammatory diseases, with experimental dosing and conditions tailored to specific study designs.
