A combination of molecular probe-tandem electrospray ionization mass spectrometry: A technique for tracing structural changes in phospholipid hydroperoxides

An ethyl-labeled phosphatidylcholine hydroperoxide (PC-OOH/Et 2) was synthesized as a molecular probe for naturally occurring PC-OOH 1. Applying the precursor ion scan mode in tandem ESI mass spectrometry at m⁄z 198, a signal of the PC-OOH/Et 2 alone could be selectively detected even in the presenc...
