Lp-PLA2 hydrolyzes BHCL only after oxidation. LC-MS profiles of monolysoCL and dilysoCL species in experimental conditions of BHCL with or without AAPH and subsequent hydrolysis by Lp-PLA2 are shown (top). LC-MS comparison of molar percentage of intact tetralinoleoyl CL (bottom, left) and monolysoCL (MCL) species, dilysoCL (DCL) species, and free fatty acids (FFA) (bottom, right) are shown for experimental conditions of BHCL with or without AAPH and subsequent hydrolysis by Lp-PLA2 (bottom, left).
