Abstract

The positional distribution of 22∶6 and 22∶5 in aquatic animal triglycerides can be predicted by simple proportionality equations of the typey=kx. The mole % 22∶6 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 % 22∶6 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 22∶6 and 22∶5.
