1. Synthesis of phosphate-containing oligosaccharides corresponding to capsular antigen structures from Haemophilus influenzae
Abstract : This thesis describes the synthesis of spacer-equipped di- and trimeric oligosaccharide structures corresponding to fragments of the capsular polysaccharides of Haemophilus influenzae types c and f. Both of these polysaccharides are of the teichoic acid type, built up by disaccharide repeating units linked via interglycosidic phosphodiester bonds. READ MORE

2. Synthesis of lactosamine-containing carbohydrate structures and development for their easy assembly and conjugation
Abstract : This thesis is based on four publications. The first chapter describes preparation of anomerically pure thioethyl-, thiophenyl-, and n-pentenyl 2-azido-2-deoxy glycosyl building blocks from easily accessible per-acetylated glycosamines. READ MORE

3. Synthesis of xyloglucan oligo- and polysaccharides with glycosynthase technology
Abstract : Xyloglucans are polysaccharides found as storage polymers in seeds and tubers, and as cross-linking glycans in the cell wall of plants. Their structure is complex with intricate branching patterns, which contribute to the physical properties of the polysaccharide including its binding to and interaction with other glycans such as cellulose.

4. On the engineering of proteins: methods and applications for carbohydrate-active enzymes
Abstract : This thesis presents the application of different protein engineering methods on enzymes and non-catalytic proteins that act upon xyloglucans. Xyloglucans are polysaccharides found as storage polymers in seeds and tubers, and as cross-linking glucans in the cell wall of plants. READ MORE
