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

    Author : Mats Andersson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : 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.

  4. 17. Biogenesis and transport of membrane proteins in the endoplasmic reticulum

    Author : Åke Elhammer; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The site of synthesis, glycosylation, processing and transport pathways for some membrane proteins in the endoplasmic reticulum from rat liver was investigated. A lipoprotein complex was isolated from the cytoplasm. READ MORE

  5. 18. Solid-phase glycoconjugate synthesis : on-resin analysis with gel-phase ¹9F NMR spectroscopy

    Author : Mickael Mogemark; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Solid-phase synthesis; protective groups; linkers; monitoring; gel-phase; 19F NMR spectroscopy; carbohydrates; oligosaccharides; glycopeptides; Organisk kemi; Organic chemistry; Organisk kemi;

    Abstract : An efficient and versatile non-destructive method to analyze the progress of solid-phase glycoconjugate synthesis with gel-phase 19F NMR spectroscopy is described. The method relies on use of fluorinated linkers and building blocks carrying fluorinated protective groups. READ MORE

  6. 19. Synthesis of inositol phosphoglycans and analogues thereof

    Author : Katinka Ruda; JS Brimacombe; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Organisk kemi; Organic Chemistry; organisk kemi;

    Abstract : This thesis describes the synthesis of inositol phosphoglycans (IPG) corresponding to glycosyl-phosphatidylinositol (GPI) anchors found on the cell surface of the parasite Leishmania. Synthesis of an IPG which is a putative second messenger for insulin, and of analogues thereof is also discussed. READ MORE

  7. 20. Structural and interaction studies of polysaccharides by NMR spectroscopy

    Author : Lena Lundqvist; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : 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. READ MORE
