Fatty Acid Nomenclature | Part 3 Lipid Foundations | Macronutrients Lecture 69

The naming of fatty acids describes the length of the chain and both the number and placement of the double bonds.

Different nomenclature is used in biochemistry and nutrition compared to chemistry. Names describe how many carbons, how many double bonds, and where the double bonds are. In biochemical naming, carbon counting starts at the methyl end. The term omega is the last letter in the Greek alphabet and in fatty acid naming tells you how many carbons away from the methyl end you are. In the literature sometimes omega is referred to a “n”, so omega fatty acids are sometimes called your “n6 fatty acids”. In chemistry naming, carbon counting starts at the carboxyl end and uses the Greek letter delta to tell you how many carbons away from the carboxyl end the double bonds exist.
