  1. 16. 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.

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

    Författare :Åke Elhammer; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : 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. LÄS MER

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

    Författare :Mickael Mogemark; Umeå universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 19. Synthesis of inositol phosphoglycans and analogues thereof

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

    Sammanfattning : 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. LÄS MER

  7. 20. Complement-dependent defence against bacterial infection. Studies in C2 deficiency

    Författare :Barbro Selander; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; antibody responses; polysaccharide antigens; vaccination; mannan-binding lectin MBL ; complement; C2 deficiency; Immunology; serology; transplantation; Immunologi; serologi;

    Sammanfattning : The complement system is critically involved in defence against bacterial infection. C2 deficiency is, apart from mannan-binding lectin (MBL) deficiency, the most common homozygous complement deficiency among Caucasians. LÄS MER
