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,
The potential of fast-atom-bombardment (f.a.b.) mass-spectrometry in the carbohydrate field was assessed with the aid of unmodified, permethylated, and peracetylated oligosaccharides and glycosphingolipids. F.a.b. spectra are presented for (o-Gal--+&GlcNAc),+(D-Man),-+D-GlcNAc, permethylated (D-Gal+
