Octadecenoic acid (cis-9)

Oleic acid; C18:1 (cis-9) Fatty acid

This product is a high purity unsaturated fatty acid that is ideal as a standard and for use in biological systems. Oleic acid is the most abundant natural monounsaturated fatty acid in plants and animals. Oleic acid and linoleic acid can modulate some of the functions of neutrophils, thereby influencing the inflammatory process.1 It inhibits protein kinase C activity in lymphocytes, the release of myeloperoxidase, and the chemotaxis of human neutrophils. It can promote necrosis and apoptosis of human lymphocytes and it has been associated with a reduction in cardiovascular disease,2 rheumatoid arthritis and a variety of cancers.3 Oleic acid has been demonstrated to be responsible for reducing blood pressure when consumed as a dietary source.4 It is an insect pheramone that is released when the insect dies and is a component of pheramones used by other animals. Oleic acid and phosphatidylethanolamine form oleoylethanolamide which has various biological functions such as anorexigenic and body fat loss properties.
