Nisinic acid is a very long chain polyunsaturated omega-3 fatty acid, similar to docosahexaenoic acid (DHA). The lipid name is 24:6 (n-3) and the chemical name is all-cis-6,9,12,15,18,21-tetracosahexaenoic acid. It is not well studied, but polyunsaturated fatty acids even longer than DHA, nisinic acid included, may hold scientific promise. ^{[1] [ vague ]} It has biological activity and is involved in the formation of DHA, but the mechanisms are still under research. ^{[2] [3] [4] [5]}
