What are omega-3 fatty acids?
Omega-3 is a polyunsaturated fatty acid with double bonds in the structure. The number in the fatty acid name indicates the location of the first unsaturated bond when starting from the methyl end of the carbon chain. The three main omega-3 fatty acids are alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA).
