Heneicosapentaenoic Acid (HPA) is a 21:5 ω-<wbr></wbr>3 fatty acid present in trace amounts in the green alga <em>B. pennata</em> and in fish oils. Its chemical composition is similar to eicosapentaenoic acid (EPA) except elongated with one carbon on the carboxyl end, placing the first double bond in the Δ HPA can be used to study the significance of the position of the double bonds in ω-<wbr></wbr>3 fatty acids. It incorporates into phospholipids and into triacylglycerol <em>in vivo</em> with the same efficiency as EPA and docosahexaenoic acid and exhibits strong inhibition of arachidonic acid synthesis from linoleic acid. HPA is a poor substrate for prostaglandin H synthase (PGHS) (cyclooxygenase) and for 5-<wbr></wbr>lipoxygenase but retains the ability to rapidly inactivate PGHS.
