| Questions And Answer | Back Directory | [Preparation]
Research on palmitoleic acid is not yet systematic, and there are few reports on its purification and preparation. Currently, the main methods used are supercritical CO2 extraction and molecular distillation. Supercritical CO2 extraction utilizes CO2 at certain pressures and temperatures to form a supercritical fluid for the extraction and separation of specific components. In the supercritical state, contacting the supercritical CO2 fluid with the substances to be separated allows for the selective extraction and separation of components with different polarities, boiling points, and relative molecular masses. Chilada et al. used this method to extract palmitoleic acid from sea buckthorn fruit oil, achieving a palmitoleic acid content of up to 55.24% in the product. Molecular distillation is a method for separating fatty acids that has emerged in recent years. Under ultra-vacuum conditions, fatty acid molecules undergo thermal motion, and different components are separated based on the distance of their free path of motion. |

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