What is PALMITOLEIC ACID?

Description

Palmitoleic acid, or (Z)-9-hexadecenoic acid, is an omega - 7 mono unsaturated 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 generally found in higher concentrations in the liver. It is biosynthesized from palmitic acid by the action of the enzyme delta-9 desaturase. A beneficial fatty acid, it has been shown to increase insulin sensitivity by suppressing inflammation, as well as inhibit the destruction of insulin-secreting pancreatic beta cells.

clear liquid

Chemical properties

PALMITOLEIC ACID, Also called cis-9-hexa decanoic acid, formula CH3(CH2)5CH:CH(CH2)7COOH. This is an unsaturated fatty acid found in nearly every fat, especially in marine oils (15–20%). At room temperature, it is a colorless liquid. Insoluble in water; soluble in alcohol and ether. Insoluble in water; soluble in alcohol and ether. Combustible.

Occurrence

Palmitoleic acid can be abbreviated as 16:1Δ⁹. Dietary sources of palmitoleic acid include a variety of animal oils, vegetable oils, and marine oils. Macadamia oil (Macadamia integrifolia) and sea buckthorn oil (Hippophae rhamnoides) are botanical sources with high concentrations, containing 17 % and 40 % of palmitoleic acid, respectively.

The Uses of PALMITOLEIC ACID

Palmitoleic Acid is a polyunsaturated fatty acid which contributes to reduced protein oxidation in mammals when added as a dietary supplement.

The Uses of PALMITOLEIC ACID

Palmitoleic acid is used in organic synthesis, and as a standard in chromatographic analysis.

Definition

ChEBI: A hexadecenoic acid with a cis-double bond at position C-9.

General Description

Palmitoleic acid is a monounsaturated fatty acid found in macadamia oil and also in blood plasma. In the human body it is produced via endogenous fat synthesis.

Biochem/physiol Actions

Palmitoleic acid is a 16-carbon, omega-7, monounsaturated fatty acid that is enriched in the triglycerides of human adipose tissue and in liver.
