Palmitoleic acid, or (9Z)-hexadec-9-enoic acid, is an omega-7 monounsaturated fatty acid (16:1n-7) with the formula CH 3 (CH 2) 5 CH=CH(CH 2) 7 COOH. It is a rare component of fats. [ 1 ] It is a common constituent of the glycerides of human adipose tissue .
The two most common omega−7 fatty acids in nature are palmitoleic acid and vaccenic acid. [1] They are widely used in cosmetics due to their moisturizing properties. Omega−7 fats are not essential fatty acids in humans as they can be made endogenously. Diets rich in omega−7 fatty acids have been shown to have beneficial health effects ...
Palmitoleic acid has 16 carbons, is found in cod liver oil, sardine oil, and herring oil, and is a cis-9-monounsaturated fatty acid. C 15 H 29 CO 2 H, IUPAC organization name ( Z )-hexadec-9-enoic acid, n-7, numerical representation of 16:1, molecular weight 254.41, melting point 5 °C, specific gravity 0.894.
Saturated fatty acids have perfectly straight chain structure. Unsaturated ones are typically bent, unless they have a trans configuration. In chemistry, particularly in biochemistry, a fatty acid is a carboxylic acid with an aliphatic chain, which is either saturated or unsaturated.
Palmitic acid (hexadecanoic acid in IUPAC nomenclature) is a fatty acid with a 16-carbon chain. It is the most common saturated fatty acid found in animals, plants and microorganisms. [ 9 ] [ 10 ] Its chemical formula is CH 3 (CH 2 ) 14 COOH , and its C:D ratio (the total number of carbon atoms to the number of carbon-carbon double bonds) is 16:0.
In biochemistry and nutrition, a monounsaturated fat is a fat that contains a monounsaturated fatty acid (MUFA), a subclass of fatty acid characterized by having a double bond in the fatty acid chain with all of the remaining carbon atoms being single-bonded. By contrast, polyunsaturated fatty acids (PUFAs) have more than one double bond.
Mink oil is also used for treating, conditioning and preserving nearly any type of leather. Botanical alternatives to mink oil as a source of palmitoleic acid include macadamia oil ( Macadamia integrifolia ) and sea buckthorn oil ( Hippophae rhamnoides ), both of which contain as much or more palmitoleic acid (17% and 19–29% respectively ...
The lipokine palmitoleic acid (C16:1n7-palmitoleate) travels to the muscles and liver, where it improves cell sensitivity to insulin and blocks fat accumulation in the liver. In addition, researchers observed that palmitoleate suppresses inflammation, which is considered by many to be a primary factor leading to metabolic disease.
