Arachidonic acid, a polyunsaturated omega-6 fatty acid, has a 20-carbon chain. Its structural composition is critical to its biological roles, from cellular signaling to inflammation. Specifically, the number of double bonds in arachidonic acid directly influences its shape and function within cell membranes.

Dihomo-γ-linolenic acid (DGLA, or C20 3n 6 fatty acid) is a polyunsaturated fatty acid that has garnered scientific interest for its nuanced role in metabolic pathways and inflammation. While often overshadowed by other omega-6s, its downstream metabolites possess powerful anti-inflammatory and anti-proliferative properties. This article delves into the biosynthesis, function, and importance of DGLA in maintaining physiological balance.

EPA, or eicosapentaenoic acid, is a 20-carbon fatty acid found abundantly in cold-water fish like salmon and mackerel. Knowing the chemical formula for omega-3 EPA is key to understanding its biological function and the health benefits it provides.

DHA comprises over 90% of the omega-3 fatty acids in the brain and is a critical structural component of the cerebral cortex, retina, and sperm. This is the long-chain, polyunsaturated omega-3 fatty acid known as docosahexaenoic acid (DHA), which is vital for human physiology and must be obtained through diet.

According to the American Heart Association, replacing saturated fats with polyunsaturated fats is a key strategy for reducing LDL ("bad") cholesterol and lowering heart disease risk. To build a healthier eating plan, it is vital to understand **what does PUFA stand for**, what they do for your body, and which foods contain them.
