What Is Heneicosapentaenoic Acid (21:5) & What Foods Can I Find It In?

Heneicosapentaenoic acid, HPA, 21:5, is a polyunsaturated conjugated fatty acid.

Its chemical composition is similar to eicosapentaenoic acid, EPA.

(EPA has been implicated in a wide range of biological activities including immunomodulation, cardiovascular and anti-cancer effects.)

HPA is found in small amounts in fish oils.

Because of the small amounts of HPA, it is unlikely that this fatty acid is of particular significance for the biological effects from these oils.
