Various glycerophospholipids (PPL) and H-D exchanged PPL analogs were analyzed using a quadrupole ion-trap, and a triple quadrupole mass spectrometer. The fragmentation pathways of phospholipids under low-energy collisionally activated decomposition were proposed. The results show that charge-remote and charge-driven are the two major fragmentation pathways that lead to the ion formation for PPLs. The pathways are governed by the steric configuration and the gas-phase basicities of the precursor ions.
