Department of Chemistry: Dissertations, Theses, and Student Research

This thesis begins with an overview of the state-of-the-art in tandem mass spectrometry (MS/MS) analysis of glycopeptides. In this introduction, the primary focus is on utilization of different ion dissociation techniques for MS/MS to obtain structural information of N-glycopeptides. This includes a discussion of the importance of complementary MS/MS methods to attain complete structural characterization of N-glycopeptides. Emerging methods involving the use of a single ion dissociation technique for complete glycopeptide connectivity analysis were also presented. Next, the application of collision-induced dissociation (CID) to provide both amino acid sequence and monosaccharide connectivity for model N-glycopeptides was discussed in detail. Implementation …
