Palmitoleic acid

Palmitoleic acid, or (9Z)-hexadec-9-enoic acid, is an omega-7 monounsaturated fatty acid with the formula CH3(CH2)5CH=CH(CH2)7COOH that is a common constituent of the glycerides of human adipose tissue. It is present in all tissues but, in general, found in higher concentrations in the liver. It is biosynthesized from palmitic acid by the action of the enzyme Stearoyl-CoA desaturase-1.

It is present in all tissues but, in general, found in higher concentrations in the liver. It is biosynthesized from palmitic acid by the action of the enzyme Stearoyl-CoA desaturase-1. Palmitoleic acid can be abbreviated as 16:1∆9. Dietary sources of palmitoleic acid include breast milk, a variety of animal fats, vegetable oils, and marine oils. Macadamia oil (Macadamia integrifolia) and sea buckthorn oil (Hippophae rhamnoides) are botanical sources with high concentrations, containing 17% and 19-29% of palmitoleic acid, respectively. It also comprises 13.55% of the fats from the fruit of the durian species Durio graveolens.
