Arachidonic acid, or arachidonic acid, abbreviated as AA or ARA, is an omega-6 polyunsaturated fatty acid, which is the counterpart of saturated arachidonic acid in peanut oil.
Arachidonic acid is an all-cis-5,8,11,14-eicosatetraenoic acid with the following chemical formula: CH3(CH2)4(CH=CH-CH2)4(CH2)2COOH, which is an unsaturated fatty acid, It contains four carbon-carbon double bonds and one carbon-oxygen double
bond, which is a high-grade unsaturated fatty acid. It is widely distributed in the animal kingdom, and a small amount exists in a certain kind of glycerides, and can also be found in glycerophospholipids. The human body can be synthesized by linoleic acid. It is inferred that it is one of the initiators of prostaglandin biosynthesis. In recent years, AA has been used in more fields, such as health care products, cosmetics, medicines and animal feed, etc.
1. Arachidonic acid plays an important role as a structural lipid combined with phospholipids in the blood, liver, muscle and other organ systems. In addition, AA is the biologically active substance of many circulating eicosanoic acid derivatives, such as prostaglandin E2 (PGE2), prostaglandin (PGI2), thromboxane A2 (TXA2), leukotriene and C4 (LTC4). Precursor. These biologically active substances have important regulatory effects on lipid protein metabolism, hemorheology, vascular elasticity, white blood cell function and platelet activation.
2. Arachidonic acid is an important substance for the development of the human brain and optic nerve. It plays an important role in improving intelligence and enhancing visual acuity.
3. Arachidonic acid has a series of physiological activities such as esterifying cholesterol, increasing blood vessel elasticity, reducing blood viscosity, and regulating blood cell function.
4. Arachidonic acid has important effects on preventing cardiovascular diseases, diabetes and tumors, etc.
