Notes: The ω-3 polyunsaturated fatty acids (PUFAs) found in fish oils provide cardiovascular benefits. Stearidonic acid is an ω-3 C18:4 PUFA. It is an intermediate in the metabolic pathway leading from α-linolenic acid (ALA) to eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).{16506} Dietary stearidonic acid increases tissue levels of EPA better than does dietary ALA.{16505} Stearidonoyl glycine consists of glycine attached at the carboxy terminus.
