Eicosapentaenoic acid (EPA or also icosapentaenoic acid) is an omega-3 fatty acid. In physiological literature, it is given the name 20:5(n-3). It also has the trivial name timnodonic acid. In chemical structure, EPA is a carboxylic acid with a 20-carbon chain and five cis double bonds; the first double bond is located at the third carbon from the omega end. It is obtained in the human diet by eating oily fish or fish oil— e.g., cod liver, herring, mackerel, salmon, menhaden and sardine. It is also found in human breast milk. [Wikipedia]. EPA is a biomarker for the consumption of salt-water fish.
