title: Predicting the positional distribution of docosahexaenoic and docosapentaenoic acids in aquatic animal triglycerides.
abstract: The positional distribution of 22ratio6 and 22ratio5 in aquatic animal triglycerides can be predicted by simple proportionality equations of the typey=kx. The mole % 22ratio6 at the 1, 2, or 3 position (y) is obtained by multiplying the proportionality constant for that position (k (1),k (2), ork (3)) times the mole % 22ratio6 in the total triglycerides (x). For fish and invertebrate triglycerides,k (1)=0.28,k (2)=2.06, andk (3)=0.66. For marine mammal blubber triglycerides,k (1)=0.94,k (2)=0.22, andk (3)=1.84. The same equations apply to both 22ratio6 and 22ratio5.
