Mass spectrometry can be used for structural determination of N-glycans, but commonly requires prior derivatisation or comparison to a library of standards. Here logically-derived sequence tandem mass spectrometry allows for assignment of native N-gl

Electrospray ionization (ESI) and matrix-assisted laser desorption ionization (MALDI) are soft ionization techniques commonly used in mass spectrometry. Although in-source and post-source decays of MALDI have been investigated extensively, the analog

N-linked glycosylation is one of the most important post translational modification of proteins. Various analytical techniques are used for the structural identification of the N-glycans released from proteins through various enzymatic and chemical m

N-linked glycosylation is one of the most important protein post-translational modifications. Despite the importance of N-glycans, the structural determination of N-glycan isomers remains challenging. Here we develop a mass spectrometry method, logic

Collision-induced dissociation (CID) of α-xylose and β-xylose were studied using mass spectrometry and quantum chemistry calculations. Three dissociation channels, namely loss of metal ions, dehydration, and cross-ring dissociation were found. The

The mechanism for the collision-induced dissociation (CID) of two sodiated N-acetylhexosamines (HexNAc), N-acetylglucosamine (GlcNAc), and N-acetylgalactosamine (GalNAc), was studied using quantum-chemistry calculations and resonance excitation in a
