The fish oil triglycerides are made up of fatty acids that are quite unique and also different from other types of foods. The above fish oil components have the following characteristics:

1. Polyunsaturated: They are made up of 6 double bonds. Fatty acids from other animals are quite saturated.
2. Omega – 3: Significant amounts of fatty acids molecules of fish are of configuration of omega-3. It is noteworthy that other animal-based foods do not contain this type of fatty acid. This fatty acid is somewhat special.

However, eggs from hen and shellfish that have been fed with seaweed may likely contain it. And in vegetables, linolenic acid is the fatty acid of unsaturated omega-3. Linolenic acid is found in walnuts, evening primrose, wheat germ and canola oils.
