ω-3 fatty acids

ω-3 fatty acids
omega-3 fatty acids unsaturated fatty acids in which the double bond closest to the methyl (omega) terminus of the molecule occurs at the third carbon from that end; they are present in marine animal fats and some vegetable oils. These fatty acids can modulate leukotriene composition, alter prostaglandin synthesis, inhibit platelet aggregation, and increase the ratio of high-density to low-density lipoproteins while lowering overall plasma lipid levels (particularly of triglycerides). There is evidence that they may inhibit some cancers. See accompanying table and illustration.
