Common NameDocosapentaenoic acid
DescriptionDocosapentaenoic acid (also known as clupanodonic acid) is an essential omega-3 fatty acid (EFA) which is prevalent in fish oils. Docosapentaenoic acid, commonly called DPA, is an intermediary between eicosapentaenoic acid (EPA, 20:5 ω-3) and docosahexaenoic acid (DHA, 22:6 ω-3). Seal oil is a rich source. There are three functions of docosapentaenoic acid. The most important is as part of phospholipids in all animal cellular membranes: a deficiency of docosapentaenoic acid leads to faulty membranes being formed. A second is in the transport and oxidation of cholesterol: clupanodonic acid tends to lower plasma cholesterol. A third function is as a precursor of prostanoids which are only formed from docosapentaenoic acid. Deficiency of this in experimental animals causes lesions mainly attributable to faulty cellular membranes: sudden failure of growth, lesions of skin and kidney and connective tissue, erythrocyte fragility, impaired fertility, uncoupling of oxidation and phosphorylation. In man pure deficiency of docosapentaenoic acid has been studied particularly in persons fed intravenously. A relative deficiency (that is, a low ratio in the body of docosapentaenoic to long-chain saturated fatty acids and isomers of docosapentaenoate) is common on Western diets and plays an important part in the causation of atherosclerosis, coronary thrombosis, multiple sclerosis, the triopathy of diabetes mellitus, hypertension and certain forms of malignant disease. Various factors affect the dietary requirement of docosapentaenoic acid. (PMID: 6469703 ).
