  3. 3. Synthesis and analysis of carbohydrates related to bacterial polysaccharides

    Detta är en avhandling från Stockholm : Department of Organic Chemistry, Stockholm University

    Författare :Hani Mobarak; Stockholms universitet.; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; carbohydrates; synthesis; conformation; NMR; O-antigen; computer-assisted structure elucidation; Organic Chemistry; organisk kemi;

    Sammanfattning : The outer surface of bacteria is composed of around 75% carbohydrates, which are vital for the bacteria to survive and communicate with the host biological system. The thesis discusses different properties of carbohydrates that are essential for understanding the bacterial behavior in biological systems. LÄS MER

  4. 4. Structure Elucidations of Bacterial Polysaccharides using NMR Spectroscopy and Bioinformatics

    Detta är en avhandling från Stockholm : Department of Organic Chemistry, Stockholm University

    Författare :Jonas Ståhle; Stockholms universitet.; [2017]
    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

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

    Detta är en avhandling från Stockholm : Karolinska Institutet, false

    Författare :Camilla Karlsson; Karolinska Institutet.; Karolinska Institutet.; [1998]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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.
