Structural determination of C18:3 FAs. (A, B) The epoxide (left panels) or cyclic peroxide (right panels) of α-linolenic acid and γ-linolenic acid were fragmented. The epoxidized and peroxidized fragments at the proximal double bond to the omega carbon are indicated by arrows and the diagnostic fragment ions from peroxidized C18:3 FAs are indicated by asterisks. The graphical fragmentation patterns for diagnostic fragment ions after peroxidation are also shown.
