  1. 6. Structure Elucidations of Bacterial Polysaccharides using NMR Spectroscopy and Bioinformatics

    Författare :Jonas Ståhle; Göran Widmalm; Evgeny Vinogradov; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbohydrates; Bioinformatics; NMR Spectroscopy; Lipopolysaccharide; Glycosyltransferase; Computer-Assisted Structure Elucidation; O-antigen; Biosynthesis; Organic Chemistry; organisk kemi;

    Sammanfattning : Carbohydrates are ubiquitous components in nature involved in a range of tasks. They cover every cell and contribute both structural stability as well as identity. Lipopolysaccharides are the outermost exposed part of the bacterial cell wall and the primary target for host-pathogen recognition. LÄS MER

  3. 7. Structures of some bacterial polysaccharides with focus on pneumococcal polysaccharides and their associated C-polysaccharide

    Författare :Camilla Karlsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Streptococcus pneumoniae; Pneumococcus; C-polysaccharide; Sphingomonas paucimoblis; Hafnia alvei; NMR spectroscopy; capsular polysaccharide; lipopolysaccharide; structure;

    Sammanfattning : This thesis describes the chemical structures of the capsular polysaccharides from Streptococcus pneumoniae types 18B, 32F, and 32A. The structure of the pneumococcal common antigen, C-polysaccharide, from a non-capsulated pneumococcal strain, CSR SCS2, is described and the structure of the C-polysaccharide associated with pneumococcal types 18B, 32F, and 32A.

  4. 8. Structural and Conformational Analysis of Bacterial Polysaccharides using NMR Spectroscopy

    Författare :Axel Furevi; Göran Widmalm; Corine Sandström; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic Chemistry; organisk kemi;

    Sammanfattning : Carbohydrates is one of the three classes of biomolecules found in nature. It is the most common one in comparison to the other two classes, lipids and proteins. However, this simple categorization does not reflect the reality since carbohydrates often are covalently linked to e.g. LÄS MER

  5. 9. NMR spectroscopy in structural and conformational analysis of bacterial polysaccharides

    Författare :Carolina Fontana; Göran Widmalm; Sven Müller-Loennies; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nuclear Magnetic Resonance; carbohydrates; O-antigen polysaccharide; organisk kemi; Organic Chemistry;

    Sammanfattning : Carbohydrates constitute one of the three major classes of biomolecules found in all living cells and, unlike nucleic acids and proteins, their polymeric structures are not based on a template. The structural diversity of these molecules confers them an enormous capacity to encode information in biological systems, acting as efficient mediators in the interaction of the cell with the environment.
