However, in a recent study, we found characteristically different HexNAc oxonium ion fragmentation patterns that depend on glycan structure. Post‐translational glycosylation of proteins play key roles in cellular processes and the site‐specific characterisation of glycan structures is critical to understanding these events. Mass spectrometry (MS) continues to play a vital role in defining the structures of N-glycans and O-glycans in glycoproteins via glycomic and glycoproteomic methodologies.The former seeks to define the total N-glycan and/or O-glycan repertoire in a biological sample whilst the latter is concerned with the analysis of glycopeptides.Recent technical developments have included … Although the species and relative abundance of oxonium ions reflect the glycan structure of origin, conventional MS/MS provides insufficient features to differentiate between glycan structures. From this, the top-ranked plausible elemental formula was calculated to be C 15 H 23 N 2 O 7 (predicted m/z, 343.1499). The workflow uses data-independent, all ion fragmentation to generate glycan oxonium ions, which are then extracted across the entirety of the chromatographic timeline to produce a glycan-specific "fingerprint" of the glycoprotein sample. 0000003167 00000 n Characterization of Glycan Structures of Chondroitin Sulfate-Glycopeptides Facilitated by Sodium Ion-Pairing and Positive Mode LC-MS/MS.
