Linoleic acid

From WikiMD's Wellnesspedia

Linoleic acid is a polyunsaturated omega-6 fatty acid. It is a colorless liquid at room temperature. In physiological literature, it has the lipid number 18:2(n-6). Linoleic acid is an essential fatty acid in mammals, meaning it cannot be synthesized internally and must be obtained from the diet.

Chemical structure[edit | edit source]

Linoleic acid is a carboxylic acid with an 18-carbon chain and two cis double bonds; the first double bond is located at the sixth carbon from the methyl end.

Sources[edit | edit source]

Linoleic acid is found in many oils, in particular safflower, sunflower, corn, and soybean oils. It is also found in the fats of meat, dairy products, and eggs.

Functions[edit | edit source]

Linoleic acid is involved in many biological functions. It is converted to arachidonic acid, which is a precursor for prostaglandins, thromboxanes, and leukotrienes, collectively known as eicosanoids. These compounds play key roles in inflammation, immunity, and other cellular functions.

Health effects[edit | edit source]

There is evidence that diets rich in linoleic acid may be beneficial for heart health. However, some studies suggest that high intakes of linoleic acid could increase inflammation and the risk of chronic diseases.
