Profiling of acylcarnitines (ACs) in tissues and biological fluids by mass spectrometry is a powerful approach to examine the impact of genetic, pharmacological, and environmental factors on intermediary metabolism. The AC pool exhibits rapid changes in composition and abundance in response to altered cellular fuel catabolism. However, the mercurial nature(More)
The [M + H](+) cations formed upon electrospray ionization of the glycerophospholipids phosphatidylcholine (PC) and phosphatidylethanolamine (PE) show distinct reactivities upon gas-phase reactions with doubly deprotonated 1,4-phenylenedipropionic acid (PDPA). PC cations undergo charge inversion via adduct formation with subsequent methyl cation and proton(More)
