  3. 17. Structural studies of some carbohydrate containing bacterial antigens

    Författare :Bengt Lindqvist; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The structure of three bacterial antigens from Klebsiella type 37, Streptococcus pneumoniae type 1 and Haemophilus influenzae type f has been studied. In the capsular polysaccharides from Klebsiella type 37 and Streptococcus pneumoniae type 1, new sugars were discovered. In the extracellular polysaccharide material from Aerococcus viridans var.

  4. 18. Determination of the structures of three bacterial polysaccharides and synthesis and use of new spacers for glycoconjugate formation

    Författare :Mats Andersson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The first part of this work describes studies on the structures of three bacterial polysaccharides, i.e., the extracellular polysaccharides of Streptococcus pneumoniae type 2 and Butyrivibrio fibrisolvens strain X6C61 and the O-antigenic side-chain of the lipopolysaccharide of Escherichia coli 086.

  5. 19. The structures of three bacterial polysaccharides and model studies on oligosaccharides and polyisoprenoids using NMR and FAB-MS

    Författare :Kerstin Hermansson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Some vicinally branched milk and blood group oligosaccharides were analyzed using nuclear magnetic resonance (NMR) spectroscopy in order to investigate NMR chemical shift changes that originate from the branching. These 13C-NMR chemical shift changes were used to calculate NMR spectra of oligo- and polysaccharides using the computer program CASPER. LÄS MER

  7. 20. Enzymes involved in biosynthesis and degradation of heparin-related polysaccharides

    Författare :Dagmar Sandbäck Pikas; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; heparin; heparan sulphate; biosynthesis; N-deacetylase N-sulphotransferase; endoglycosidase; heparanase; Biokemi; Biochemistry; Biokemi; Medical and Physiological Chemistry; medicinsk och fysiologisk kemi;

    Sammanfattning : Heparin and heparan sulphate (HS) are structurally related polysaccharides of the glycosaminoglycan type. As the glycan moiety of proteoglycans, they exist covalently linked to various core proteins. LÄS MER
