18. Structural Studies of O-antigen polysaccharides, Synthesis of 13C-labelled Oligosaccharides and Conformational Analysis thereof, using NMR Spectroscopy
Sammanfattning : In order to understand biological processes, to treat and diagnose diseases, find appropriate vaccines and to prevent the outbreak of epidemics, it is essential to obtain more knowledge about carbohydrate structures. This thesis deals with structure and conformation of carbohydrates, analysed by NMR spectroscopy and MD simulations. LÄS MER
19. Metals in Dynamic Chemistry: Selection & Catalysis
Sammanfattning : In the adaptation to the oxidative environment on earth, metals played a crucial role for the evolution of life. The presence of metals also allowed access to advanced functions due to their unique coordination sphere and reactivity. LÄS MER
20. Sialic acid-dependent binding specificities of Helicobacter pylori and influenza virus. Importance of different parts of the binding sequences
Sammanfattning : Many viruses and bacteria adhere to host cell glycoconjugates in a specific manner, utilizing selected carbohydrate sequences. The aim of this work was to investigate at a molecular level the interactions of two important human pathogens, influenza virus and Helicobacter pylori, with sialylated carbohydrate structures.
