Occurrence and chemical structure of nonmethylene‐interrupted dienoic fatty acids in american oysterCrassostrea virginica

Abstract

The American oyster,Crassostrea virginica, was found to contain structurally homologous nonmethylene-interrupted dienoic (NMID) fatty acids. The major C₂₀ and C₂₂ nonmethylene-interrupted dienoic fatty acid isomers were shown to occur as two pairs of homologues 5,13–20∶2 with 7,15–22∶2 and 5,11–20∶2 with 7,13–22∶2. A combination of analytical procedures was required for conclusive structure determination.
