Description
Alpha-linolenic acid (ALA) is an essential omega-3 fatty acid found in nuts such as walnuts.ALA is a carboxylic acid with an 18-carbon chain and three cis double bonds. The first double bond is located at the third carbon from the methyl end of the fatty acid chain, known as the n end. Thus, α-linolenic acid is a omega-3 fatty acid.
Uses
Alpha-linolenic acid is most commonly used for diseases of the heart and blood vessels, such as hardening of the arteries, heart disease, and high blood pressure. It is also used for other conditions, but there is no good scientific evidence to support most of these uses.
Health effects
Alpha-linolenic acid is thought to decrease the risk of heart disease by helping to maintain normal heart rhythm and pumping. It might also reduce blood clots.Dietary ALA intake can improve lipid profiles by decreasing triglycerides, total cholesterol, high-density lipoprotein, and low-density lipoprotein.
