Fig. 5 MS2 spectrum for identification of a precursor ion as a glycosylated peptide The peak at m/z 1198.39 marked with an asterisk is produced through losing a deoxyhexose from double-charged precursor ion 1271.58. The diagnostic oxonium ions are highlighted in red and the neutral losses are indicated in blue lines. HexNAc, Hex and Pent are the abbreviations for N-acetylhexosamine, hexose and pentose, respectively.
