What Is Heneicosapentaenoic Acid?

Heneicosapentaenoic acid, HPA, 21:5, is a polyunsaturated conjugated fatty acid. Its chemical composition is similar to eicosapentaenoic acid, EPA.

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.
