Palmitoleic acid
Cis-9-palmitoleic acid, also known as palmitoleate or (Z)-9-hexadecenoic acid, is a member of the class of compounds known as long-chain fatty acids. Long-chain fatty acids are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Thus, cis-9-palmitoleic acid is considered to be a fatty acid lipid molecule. Cis-9-palmitoleic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Cis-9-palmitoleic acid can be found in a number of food items such as mixed nuts, carrot, hedge mustard, and chanterelle, which makes cis-9-palmitoleic acid a potential biomarker for the consumption of these food products. Cis-9-palmitoleic acid can be found primarily in most biofluids, including urine, blood, saliva, and feces, as well as in human adipose tissue, prostate and skeletal muscle tissues. Cis-9-palmitoleic acid exists in all living species, ranging from bacteria to humans. Moreover, cis-9-palmitoleic acid is found to be associated with isovaleric acidemia. Palmitoleic acid, or (9Z)-hexadec-9-enoic acid, is an omega-7 monounsaturated fatty acid (16:1n-7) with the formula CH3(CH2)5CH=CH(CH2)7COOH that is a common constituent of the glycerides of human adipose tissue. Present in all tissues, it is generally found in higher concentrations in the liver. Macadamia oil (Macadamia integrifolia) and sea buckthorn oil (Hippophae rhamnoides) are botanical sources of palmitoleic acid, containing 22 and 40\\\\\% respectively.

FA(16:1)
Palmitoleic acid (FA 16:1), also known as hexadecenoic acid, is a monounsaturated omega-7 fatty acid with a 16-carbon chain and a double bond at the 9th position. In biological terms, palmitoleic acid serves several important functions: 1. **Energy Source:** Like other fatty acids, palmitoleic acid is a significant source of energy. It can be oxidized through beta-oxidation to produce ATP, the energy currency of the cell. 2. **Cell Membrane Structure:** Palmitoleic acid is a component of phospholipids, which are major constituents of cell membranes. The presence of monounsaturated fatty acids like palmitoleic acid helps maintain the fluidity and flexibility of cell membranes, which is crucial for various cellular processes. 3. **Lipid Signaling:** Palmitoleic acid and its derivatives can act as signaling molecules. For example, it is converted into the lipid mediator called palmitoleoyl-lysophosphatidylcholine (LPC), which plays a role in inflammation and blood clotting. 4. **Insulin Sensitivity:** Palmitoleic acid has been shown to improve insulin sensitivity, which is important for glucose metabolism and can help in the prevention and treatment of type 2 diabetes. 5. **Inflammation Modulation:** Some studies suggest that palmitoleic acid may have anti-inflammatory effects, which could be beneficial in reducing the risk of chronic diseases associated with inflammation. 6. **Skin Health:** Palmitoleic acid is naturally present in the skin and is considered a component of the skin's surface lipids, contributing to the skin's barrier function and helping to prevent water loss. 7. **Biosynthesis of Other Lipids:** Palmitoleic acid serves as a precursor for the synthesis of other complex lipids, including prostaglandins and other eicosanoids, which are involved in a wide range of physiological processes such as inflammation and blood pressure regulation. 8. **Cardiovascular Health:** The consumption of monounsaturated fatty acids like palmitoleic acid is often associated with a lower risk of cardiovascular diseases, although the direct role of palmitoleic acid in this context is still under investigation. It's important to note that while palmitoleic acid has these potential biological functions, the overall impact on health can depend on the balance of fatty acids in the diet and the context of the individual's overall metabolic health.
