Linolenic acid

Linolenic Acid

Linolenic acid (pronounced: li-no-LEN-ic acid) is a type of polyunsaturated fat that is essential for human health. It is an omega-3 fatty acid, which means it is one of the "good" fats that are necessary for the body to function properly.

Etymology

The term "linolenic" is derived from the Greek word "linon," which means flax, and the Latin word "oleum," which means oil. This is because linolenic acid was first isolated from the oil of flax seeds.

Function

Linolenic acid is used by the body to produce eicosanoids, which are signaling molecules that have various physiological functions. These include regulating inflammation and immune responses. Linolenic acid is also important for maintaining the health of the skin and hair, and it plays a role in the proper functioning of the nervous system.

Sources

Linolenic acid is found in a variety of foods, including flax seeds, chia seeds, hemp seeds, walnuts, and certain types of fish, such as salmon and mackerel. It can also be obtained from dietary supplements.
