wherein
the unsaturated fatty acid ethyl esters have a double bond at position 7 in the carbon chain from the reduced end of the fatty acid ethyl ester, and
wherein
the unsaturated fatty acid ethyl esters are present in an amount that is at least 50% by weight of the composition.
2. The composition of claim 1 , wherein the unsaturated fatty acid ethyl esters are present in an amount that is at least 55% by weight of the composition.
3. The composition of claim 1 , wherein the unsaturated fatty acid ethyl esters are present in an amount that is at least 60% by weight of the composition.
4. The composition of claim 1 , wherein the unsaturated fatty acid ethyl esters are present in an amount that is at least 65% by weight of the composition.
