The product ion mass spectra of reference OO-HpODE-TG isomers (A–L). Reference OO-HpODE-TG isomers were dissolved in methanol containing 0.1 mM sodium acetate (1 µM) and infused directly into the MS/MS system at a flow rate of 10 μL/min. Insets show the speculated fragmentation patterns of OO-HpODE-TG isomers
