Linoleic acid CAS#60-33-3
Linoleic acid is named cis-9, 12-octadecadienoic acid, can also use △ to denote double bond, thus being named △ 9, 12-octadecadienoic acid. Alternatively, it can be simply expressed as 9C, 12C-18: 2 or C18: 2.
Linoleic acid in foods is important for human body to maintain many physiological functions such as the synthesis of phospholipids and other lipid metabolism, etc., being capable f significantly lower the effect of serum cholesterol. It can correct the growth arrest, skin and hair abnormalities, abnormal serum and adipose tissue composition of experimental animals due to lack of essential fatty acids. Lack of it in human beings can affect cell membrane function. Lack in infants can cause eczema. It is currently the major unsaturated fatty acids used to prevent and treat hyperlipidemia. Plant fat is the main source of linoleic acid, of which soybean oil, corn oil and cottonseed oil content is particularly rich. The content in vegetable oil (except palm oil), fish fat and poultry fat is also high. It is generally recommended that the amount of dietary linoleic acid should be equivalent to more than 2% to 3% of the total dietary calories.

Product Application of Linoleic acid CAS#60-33-3
Linoleic acid is an essential ω-6 polyunsaturated fatty acid (PUFA). It is the most abundant PUFA in a variety of foods, and dietary sources of linoleic acid include vegetable oils, meats, nuts, seeds, and eggs. Linoleic acid (30 μM) increases migration of IEC-6 rat intestinal epithelial cells in a wound healing assay. Rats fed a linoleate-deficient diet exhibit decreased body weight and an increased ratio of eicosatrienoate to arachidonate in liver and serum phospholipids compared with rats fed a control diet, as well as mild scaling of forepaw skin.
