Message definition (Omega-3 fatty acid)
Three omega−3 fatty acids are important in human physiology, α-linolenic acid (18:3, ''n''-3; ALA), eicosapentaenoic acid (20:5, ''n''-3; EPA), and docosahexaenoic acid (22:6, ''n''-3; DHA). These three [[polyunsaturated|polyunsaturates]] have either 3, 5, or 6 double bonds in a carbon chain of 18, 20, or 22 carbon atoms, respectively. As with most naturally-produced fatty acids, all double bonds are in the ''[[cis-trans isomerism|cis]]''-configuration, in other words, the two hydrogen atoms are on the same side of the double bond; and the double bonds are interrupted by [[methylene bridge]]s (-{{chem|CH|2}}-), so that there are two single bonds between each pair of adjacent double bonds.
