Linoleic Acid
Linoleic acid ((9Z, 12Z)-octadeca-9,12-dienoic acid or C18:2 (n-6)) is a polyunsaturated fatty acid of 18 carbon atoms. Linoleic acid is rich in vegetable oils such as cottonseed oil, sunflower oil, safflower oil, soybean oil and maize oil.
Linoleic acid is an essential fatty acid for humans. It is an approved food additive and dietary supplement. It serves as a precursor for the biosynthesis of phospholipids, neutral lipids and cholesterol esters and plays many important physiological roles, such as regulating membrane potential by being the cell membrane component. One of the symptoms caused by the deficiency of linoleic acid is scaly dermatitis.
Incorporating linoleic acid-rich plant oils into grain-rich animal feed is employed to meet essential fatty acid requirements for farm animals' growth and development.
Various industries, including paint and personal care industries, has been used linoleic acid in product formulations.
Linoleic acid content varies with algal species. In Sargassum species, linoleic acid level ranges from 3 to 9%. A high level of linoleic acid was reported in a green algal isolate, Ulva lactuca.
Certain oleaginous yeast species belonging to Kluyveromyces and Trichosporon genus are excellent producers of linoleic acid.
