  1. 1. Membrane protein proteomics - Novel method for membrane protein identification and quantification

    Författare :Maria Bentz; Institutionen för immunteknologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biokemisk teknik; mebran; steroider; Lipider; membranes; steroids; Lipids; enzymologi; Proteiner; Membrane proteins; Proteomics; Proteinase K; N-terminal labelling; Relative Quantitation; Database search; Cancer; Cytology; oncology; cancerology; Cytologi; onkologi; cancer; enzymology; Proteins; Biochemical technology;

    Sammanfattning : Membrane proteins are fairly refractory to digestion especially by trypsin. Less specific proteases like elastase and pepsin are much more effective. However database searching using non-tryptic peptides is much less effective due to the lack of charge localisation at the N- and C-termini and the absence of sequence specificity. LÄS MER

  3. 2. The plant respiratory chain: Redox responses and catalytic definition of alternative pathways

    Författare :Daniela Geisler; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; enzymology; Proteins; Kärlväxters fysiologi; Physiology of vascular plants; Växtekologi; Plant ecology; Växtbiokemi; Plant biochemistry; respiratory chain; plant mitochondria; nitrogen; NADPH dehydrogenase; NADH dehydrogenase; alternative oxidase; calcium; Proteiner; enzymologi; Bioenergetics; Bioenergetik; Lipids; steroids; membranes; Lipider; steroider; mebran;

    Sammanfattning : The respiratory chain of plants contains both proton-pumping enzymes that conserve energy and non-proton-pumping alternative enzymes that bypass the sites of energy conservation. In addition to the proton-pumping complex I, plant mitochondria contain alternative type II NAD(P)H dehydrogenases, which allow oxidation of NADH and NADPH from the matrix and the cytosol. LÄS MER

  4. 3. Amylopectin - Interactions with Lipids and Proteins

    Författare :Henrik Lundqvist; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; binding isotherm; isothermal titration calorimetry; differential scanning calorimetry; retrogradation; alpha-lactalbumin; beta-lactoglobulin; whey protein; surfactant; lipid; exterior chain length; barley; potato; starch; amylopectin; amylose; Food and drink technology; Livsmedelsteknik; Proteins; enzymology; Proteiner; enzymologi; Lipids; steroids; membranes; Lipider; steroider; mebran;

    Sammanfattning : Starch is a common ingredient in many products, influencing properties such as viscosity, stability, sensory properties and appearance. These properties and how they change with time in the process called retrogradation are dependent on the structure of starch and its interaction with other components such as lipids and proteins.

  5. 4. Early steps of Eicosanoid precursor absorption and tissue distribution

    Författare :Tor Melin; Lund Medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lipids; mebran; steroider; Lipider; steroids; membranes; Gastro-enterology; Gastroenterologi;

    Sammanfattning : Eicosanoids are important for a wide range of physiological and pathophysiological processes.How their essential fatty acid precursors are absorbed and tissue distributed is not well charactherized. When given orally to rats, arachidonic acid (20:4) was retained in the small intestine to a larger extent than linoleic acid (18:2). LÄS MER

  7. 5. 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
