21. Affinity Biosensors for Carbahydrate-Protein Interactions using Surface Plasmon Resonance
Sammanfattning : There is an increasing need for fast, accurate, and easy-to-use biosensors for applications in environmental, food, and pharmaceutical industry. In these thesis the interactions between immunoglobulins and lectins with their corresponding carbohydrate antigens are studied using surface plasmon resonance (SPR). LÄS MER
22. Structural and interaction studies of polysaccharides by NMR spectroscopy
Sammanfattning : In this thesis, polysaccharides of different origins have been investigated by NMR spectroscopy with regard to structures and interactions. In paper I, hydrogen bonding interactions in kappa- (κ) and kappa/mu- (κ/μ) hybrid carrageenan oligosaccharides were studied by NMR spectroscopy of hydroxy protons. LÄS MER
23. Syntheses of naturally occurring fatty acid esters of sucrose and heptose-containing oligosaccharides found in the Salmonella Ra core
Sammanfattning : Nine sucrose esters, acylated in the glucopyranosyl moiety, have been synthesized from the same precursor, 3-0-allyl-3',4',6'-tri-0-benzyl-4,6-0- (4-metoxybenzylidene)sucrose. The sucrose esters synthesized include the major compounds found in tobacco and potato plants, i. e. LÄS MER
24. Structural studies towards the understanding of biosynthesis of the lipopolysaccharide of Haemophilus influenzae
Sammanfattning : The thesis Structural studies towards the understanding of biosynthesis of the lipopolysaccharide of Haemophilus influenzae involves structural investigation of LPS of four different H. influenzae strains, RM.118-28, RM.118, RM118-26 and RM. LÄS MER
25. Structural and biochemical insights into biosynthesis and degradation of N-glycans
Sammanfattning : Carbohydrates are a primary energy source for all living organisms, but importantly, they also participate in a number of life-sustaining biological processes, e.g. cell signaling and cell-wall synthesis. The first part of the thesis examines glycosyltransferases that play a crucial role in the biosynthesis of N-glycans. LÄS MER
