title: Mass spectrometric discrimination between per-O-acetylated aldopentoses applied to an oligosaccharide.
abstract: Unimolecular decomposition spectra of oxonium ions from peracetylated pentoses can be used for identification purposes. The fast-atom bombardment mass spectra of an oligosaccharide with a pentose residue at the non-reducing terminus also contain this oxonium ion, which allows identification of this monosaccharide residue by a tandem mass spectrometry experiment. The applicability of this method is demonstrated using a xylopentaose.
