  1. 1. The advantages of being small Glycosyltransferases in many dimensions and glycolipid synthesis in Mycoplasma Pneumoniae

    Detta är en avhandling från Stockholm : Institutionen för biokemi och biofysik

    Författare :Maria Rosén Klement; Stockholms universitet.; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Glycosyltransferase; lipid; membrane; glycolipid; ACC; PLS-DA; NATURAL SCIENCES Chemistry Biochemistry; NATURVETENSKAP Kemi Biokemi; biokemi; Biochemistry;

    Sammanfattning : The synthesis and breakdown of sugars is one of the most important functions in Nature. Consequently, sugar structures are used both as energy storage and as building blocks to stabilise and protect the cell. The formation of these structures is performed by glycosyltransferases (GT), an enzyme group structurally conserved within all kingdoms. LÄS MER

  2. 2. Glycoconjugates Solid-phase synthesis and biological applications

    Detta är en avhandling från Umeå : Kemi

    Författare :Fredrik Wallner; Umeå universitet.; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Glycoconjugate; Glycolipid; Solid-phase synthesis; Glycosylation; Gel-phase 19F-NMR spectroscopy; Fluorinated linker; Carbohydrat array; CD1; NATURAL SCIENCES Chemistry Organic chemistry; NATURVETENSKAP Kemi Organisk kemi;

    Sammanfattning : Glycoconjugates are biologically important molecules with diverse functions. They consist of carbohydrates of varying size and complexity, attached to a non-sugar moiety as a lipid or a protein. Glycoconjugate structures are often very complex and their intricate biosynthetic pathways makes overexpression difficult. LÄS MER

  3. 3. Plant pathogen defense: Signalling, resistance and cell death

    Detta är en avhandling från Umeå : Kemi

    Författare :Oskar N. Johansson; Göteborgs universitet.; Gothenburg University.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Pseudomonas; cell death; pathogens; plant defense; hypersensitive response; glycolipid; reactive oxygen species; blumeria graminis; erysiphe pisi;

    Sammanfattning : Pathogenic microorganisms are present everywhere in nature and infect both animals and plants. Phytopathogenic microorganisms cause diseases on plants, and are responsible for crop loss amounting in the order billions of dollars annually. LÄS MER

  4. 4. Chemical basis of ABO subgroups

    Detta är en avhandling från Umeå : Kemi

    Författare :Lola Svensson; Göteborgs universitet.; Gothenburg University.; [2011]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ABO; subgroups; glycolipid; para-Forssman; Forssman; Forssman synthetase;

    Sammanfattning : Despite the ABO histo-blood group system being the most biologically significant in humans the chemical structures that define its various phenotypes still remain largely unresolved. Like all blood group systems there is a significant range in the amount of antigen present on the red cells of an individual and there exists a range of so-called “weak” phenotypes represented by decreasing expression of A or B antigens.

  5. 5. Synthesis of Conformationally Restricted Oligosaccharides

    Detta är en avhandling från Organic Chemistry, Lund University

    Författare :Michael Wilstermann; Lunds universitet.; Lund University.; [1997]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Streptococcus suis; E. coli; neoglycolipid; ganglioside-lactam; xylose; methylene acetal; sialic acid; Conformational Restriction; galabiose; Organic chemistry; Organisk kemi;

    Sammanfattning : Gangliosides are sialic acid-containing glycosphingolipids that often are present in increased amounts on tumor cells. Since the gangliosides are hydroxy-acids, they can form lactones. The lactones have been suspected to be more immunogenic than the open forms, but are in practise poor immunogens due to their ease of hydrolysis. LÄS MER
