Figure 4

Structural determination of the PUFAs with four or more double bonds. (A, B) Fragmentation patterns of cyclic peroxide of arachidonic acid (ARA) (A) and cis-4 DTA (B) are shown. (C, D) Fragmentation patterns of highly unsaturated FA (cyclic peroxide), eicosapentaenoic acid (EPA) containing five double bonds (C) and docosahexaenoic acid (DHA) with six double bonds (D) are shown. The diagnostic fragment ions are indicated by asterisks.
