Metabolite Identification
Common NamePalmitoleic acid
DescriptionPalmitoleic 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. Palmitoleic acid is found to be associated with isovaleric acidemia, which is an inborn error of metabolism.

Enzymes

General function:
Involved in biosynthetic process
Specific function:
In fatty acid biosynthesis chain termination and release of the free fatty acid product is achieved by hydrolysis of the thio ester by a thioesterase I, a component of the fatty acid synthetase complex. The chain length of the released fatty acid is usually C16. However, in the mammary glands of non-ruminant mammals, and in the uropygial gland of certain waterfowl there exists a second thioesterase which releases medium-chain length fatty acids (C8 to C2) (By similarity).
