  1. 16. Magnesium Chelatase: Insights into the first Step of Chlorophyll Biosynthesis

    Författare :Nick Sirijovski; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electron microscopy; Proteobacteria; Mutants; Rhodobacter capsulatus; Tetrapyrrole; Plant biochemistry; Växtbiokemi; Biochemistry; Metabolism; Biokemi; metabolism; Proteins; enzymologi; enzymology; Proteiner; Chlorophyll biosynthesis; AAA proteins; Magnesium chelatase; Barley; ATPase;

    Sammanfattning : The enzyme magnesium chelatase inserts magnesium into protoporphyrin IX (Proto) to produce to magnesium protoporphyrin IX, the first unique intermediate of the chlorophyll biosynthetic pathway. Magnesium chelatase is composed of three distinct proteins termed I (molecular weight ~40 kDa), D (~70 kDa) and H (~140 kDa). LÄS MER

  3. 17. Regulation of bile acids by prebiotic food components : Studies in rat caecum and in serum of mice and humans

    Författare :Tannaz Ghaffarzadegan; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bile acids; Dietary fibre; Fat; Pectin; Guar gum; Barley; Lingonberry; Turmeric; Short-chain fatty acids; Gut microbiota; Caecum; Serum; Rat; Mice; Humans; GC-FID; UHPLC-MS;

    Sammanfattning : Bile acids (BA) are formed from cholesterol in the liver and, apart from being part of fat digestion, they also act as signalling molecules in several health-related physiological processes. BA composition is regulated by gut microbiota as well as dietary fibre (DF) and fat in the diet. LÄS MER

  4. 18. Plasma Membrane Proteomics and Functional Characterization & Expression Profiling of Plant Aquaporins

    Författare :Erik Alexandersson; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Växtbiokemi; Plant biochemistry; phosphorylation; barley; GFP; GUS; quantitative real-time reverse transcriptase PCR; microarray; aquaporin; MIP; Arabidopsis; plasma membrane; proteomics;

    Sammanfattning : In order to identify integral and peripheral proteins associated with the plasma membrane (PM), highly purified Arabidopsis PMs were analyzed by mass spectrometry. In total, 238 putative PM proteins were identified, of which 114 were predicted to have transmembrane domains or to be PM-anchored. LÄS MER

  5. 19. 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.

  7. 20. Process Development of Bioethanol Production from Wheat and Barley Residues Steam Pretreatment and SSF

    Författare :Marie Linde; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbochemistry; Kemiteknik och kemisk teknologi; Chemical technology and engineering; metabolism; Biokemi; Metabolism; Biochemistry; Barley straw; Wheat straw; DDGS; Fermentation; SSF; Enzymatic hydrolysis; H2SO4; Ethanol production; Steam pretreatment; petrochemistry; fuels and explosives technology; Petrokemi; bränslen; sprängämnen; Wood; pulp and paper technology; Pappers- och massateknik; Biotechnology; Bioteknik;

    Sammanfattning : Bioethanol has received increasing attention as an alternative to petrol due to the current dependency on supplies from other countries and due to the increased concentration of the greenhouse gas carbon dioxide in the atmosphere. In this thesis, the development of 2nd generation production processes for bioethanol production from the lignocellulosic part of biomass is discussed. LÄS MER
