Tandem mass spectrometry (MS/MS) and the fast atom bombardment (FAB) ionization method were used to determine the structures of phosphonosphingolipids. Water-soluble components, aminoethylphosphonic acid and N-methylaminoethylphosphonic acid, were distinguished easily by the ions at m/z 126 and 140,
It was found that in the fast atom bombardment mass spectra of some asymmetric secondary alcohols and amines, wben a pair of enantiomers, such as (2R,3R)-and (2S,2S)-2,3-diacetoxysuccinic anhydride and (2R,3R)-and (2S,3S)-2,3dibenzoyloxysuccinic anhydride, were used as reagents, the relative abundaa
The determination of cytidine 3',5'-cyclic monophosphate-specific phosphodiesterase activity by means of fast-atom bombardment (FAB) mass spectrometry with mass-analysed ion kinetic energy (MIKE) spectrum scanning is described. Initial efforts to determine the activity of the enzyme by this method w
