Heneicosapentaenoic Acid (HPA; Item No. <span class=/itemid/>10670</span>) is a 21:5 ω-3 fatty acid present in trace amounts in green algae and in fish oils. Its chemical composition is similar to eicosapentaenoic acid (EPA; Item No. <span class=/itemid/>90110</span>) 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 n-3 fatty acids. It incorporates into phospholipids and into triacylglycerol in vivo with the same efficiency as EPA and docosahexaenoic acid (DHA; Item No. <span class=/itemid/> 90310</span>) and exhibits strong inhibition of arachidonic acid (Item No. <span class=/itemid/>90010</span>) synthesis from linoleic acid (Item No. <span class=/itemid/>90150</span>). Heneicosapentaenoic acid ethyl ester is a more lipophilic, stabilized form of the free acid.
