  1. 31. Vitreoscilla Haemoglobin - Peroxidase Activity and Metabolic Aspects

    Författare :Malin Kvist; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metabolism; Biokemi; Metabolism; Biochemistry; Naturvetenskap; Natural science; lipid peroxidation; hypoxia; salt stress; Escherichia coli; Lactococcus lactis; hydrogen-bonding network; proximal site; mutations; Vitreoscilla haemoglobin; peroxidase activity; Proteins; enzymology; Proteiner; enzymologi;

    Sammanfattning : The function of non-vertebrate haemoglobins (Hbs) appears more diverse than that of vertebrate Hbs, possibly reflecting the various demands to be met among their hosts. Sharing structural features with other haem proteins/enzymes, Hbs display a qualitative overlap in activities with functions extending beyond oxygen transport/storage. LÄS MER

  3. 32. Hormone-sensitive lipase: Molecular analyses of the human gene; structural and evolutionary aspects on expression, alternative splicing and cold adaptation

    Författare :Henrik Laurell; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; enzymologi; Proteiner; Proteins; enzymology;

    Sammanfattning : Hormone-sensitive lipase (HSL) is a key enzyme in adipose tissue that hydrolyses stored fat (triacylglycerol). The activity of HSL is under strict hormonal and neural control. LÄS MER

  4. 33. Beta-Lactamase in Haemophilus ducreyi: Purification, Characterization, and Mutagenesis

    Författare :Ratana Lawung; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biokemi; Metabolism; Biochemistry; enzyme calorimeter; site-directed mutagenesis; ampicillin resistance plasmid; Haemophilus ducreyi; TEM-1 b-lactamase; metabolism; Proteins; enzymology; Proteiner; enzymologi; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Chancroid caused by Haemophilus ducreyi, has been described as a significantly predisposing factor of HIV heterosexual transmission in an endemic region of both diseases. Antibiotic resistances are extensively found in H. ducreyi and many of the resistances are due to the presence of resistance plasmids. LÄS MER

  5. 34. 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. 35. Enzymatic synthesis of lipids containing omega-3 fatty acids

    Författare :Ann-Marie Lyberg; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; enzymologi; Proteiner; enzymology; Proteins; Enzymes; DHA; EPA; Biotechnology; Bioteknik;

    Sammanfattning : Docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are omega-3 fatty acids, which have health promoting effects. Since they are highly prone to oxidation, they should be protected, in particular DHA. LÄS MER
