Linoleic acid is called essential fatty acid because it cannot be synthesized by the human body itself or is rarely synthesized, and it must be obtained from food. Linoleic acid has attracted much attention because it can reduce blood cholesterol and prevent atherosclerosis. It is found that cholesterol must be combined with linoleic acid to function and metabolize normally in the body.

If linoleic acid is lacking, cholesterol will combine with some saturated fatty acids, causing metabolic disorder, depositing on the blood vessel wall, gradually forming atherosclerosis, and causing cardiovascular and cerebrovascular diseases. Therefore, linoleic acid can prevent or reduce the incidence of cardiovascular and cerebrovascular diseases.

Linoleic acid, a fatty acid. The molecular formula is CH3 (CH2) 4ch = chch2ch = ch (CH2) 7cooh. The scientific name is cis, cis -9, 12- octadecadienoic acid. Linoleic acid, together with other fatty acids, exists in animal and vegetable oils in the form of glyceride, which is the main component of linseed oil and cottonseed oil in drying oil and semi-drying oil.

Linoleic acid CH3 (CH2) 4Ch = CHCH2 CH = CH (CH2) 7COOH, an unsaturated fatty acid. It is the main component in drying oil and semi-drying oil, such as linseed oil and cottonseed oil in the form of glyceride. The contents of several vegetable oils are relatively high, accounting for 76%-83% of the total fatty acids of safflower seed oil.
