  1. 1. Digestion and absorption of galactolipids

    Författare :Lena Ohlsson; Lund Medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gastro-enterology; Pancreatic lipase related proteins.; Pancreatic lipase; Monogalactosyldiglyceride; Lipolytic enzymes; Galactolipids; Essential fatty acids; Digestion; Digalactosyldiglyceride; Colipase; Chylomicron; Bile salt stimulated lipase; Carboxyl ester lipase; Gastroenterologi; Proteins; enzymology; Proteiner; enzymologi; Lipids; steroids; membranes; Lipider; steroider; mebran;

    Sammanfattning : Galactolipids: digalactosyldiglyceride (DGalDG), monogalactosyldiglyceride (MGalDG) and sulfoquinovosyldiglyceride (SQDG) are the major lipid components in thylakoid membranes of chloroplasts i.e. the site of photosynthesis in plants. LÄS MER

  3. 2. One key to two doors : Dual targeting peptides and membrane mimetics

    Författare :Weihua Ye; Lena Mäler; Göran Kalsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; : Dual targeting peptides; protein import; mitochondria and chloroplasts; bicelles; galactolipids; NMR spectroscopy; Biophysics; biofysik;

    Sammanfattning : A targeting peptide at the N-terminus of a precursor protein usually directs the protein synthesized in the cytosol to a specific organelle in the cell. Interestingly, some targeting peptides, so-called dual targeting peptides (dTPs) can target their protein to both mitochondria and chloroplasts. LÄS MER

  4. 3. Structure and lipid interactions of membrane-associated glycosyltransferases : Cationic patches and anionic lipids regulate biomembrane binding of both GT-A and GT-B enzymes

    Författare :Scarlett Szpryngiel; Lena Mäler; Marcelo Guerins; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; glycosyltransferase; monotopic membrane proteins; galactolipids; NMR; chitin synthase; DGD2; LPS; WaaG; MIT domain; Biophysics; biofysik;

    Sammanfattning : This thesis concerns work on structure and membrane interactions of enzymes involved in lipid synthesis, biomembrane and cell wall regulation and cell defense processes. These proteins, known as glycosyltransferases (GTs), are involved in the transfer of sugar moieties from nucleotide sugars to lipids or chitin polymers. LÄS MER

  5. 4. Biophysical studies of membrane associated biomolecular interactions

    Författare :Weihua Ye; Arnold Maliniak; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Membrane associated interactions play important roles in various biological processes. The aim of this thesis is to study two types of membrane associated interactions by using biophysical methods, particularly NMR. First, the interaction of a targeting peptide and a receptor attached to membrane has been studied. LÄS MER

  7. 5. Synthesis and Development of Methods for Preparation of Inositolphosphoglycans, Glycoglycerolipids and Glycerophospholipids

    Författare :Jan Lindberg; Bertram Fraser-Reid; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis describes the synthesis of a series of myo-inositol-containing oligosaccharides, and the exploration of using the chiral epoxide (S)-glycidol in short synthetic routes to glycoglycerolipids and glycerophospholipids.In chapter 2, synthesis of the core heptasaccharyl myo-inositol Galp(α1-6)Galp(α1 -3)Galf(β1-3)[Glcp(α1-P04-6)Manp](α1-3)Manp(α1-4)GlcNp(α1-6)Ins-1-P04, found in the lipophosphoglycans of Leishmania parasites, is described.
