  1. 1. Hydrogen Bonding in Liquid Alcohols

    Author : Per Sillrén; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; Hydrogen Bonded Liquids; Physics of liquids; Diffraction; Monte Carlo Simulation; Alcohols; Neutron Scattering; EPSR;

    Abstract : Hydrogen bonded (H-bonded) materials, such as water, alcohols, sugars, and even DNA, are extremely important for biology, as well as chemical industry. Alcohols are used as solvents in paints, in perfumes, as cleaners, anti-freezers, or as an alternative to petrol in combustion engines. READ MORE

  2. 2. Vitreoscilla Haemoglobin - Peroxidase Activity and Metabolic Aspects

    Author : Malin Kvist; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 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;

    Abstract : 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. READ MORE

  3. 3. Molecular Interaction in Aqueous Solutions : Effects of Temperature and Solutes on Surface Structure and Hydrogen Bonding in Water

    Author : Clara-Magdalena Saak; Carl Caleman; Olle Björneholm; Nicusor Timneanu; Edwin Kukk; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Intermolecular forces in liquids can give rise to complex emergent structures, particularly in water, where hydrogen bonding causes the formation of extended networks, and surfaces, where intermolecular structures can be distinctly different from the bulk, leading to unique properties and behaviours. While such structures have been studied in detail, it is still relatively unknown how such structures respond and adapt to external changes to their environment. READ MORE

  4. 4. Studies of carbohydrate structure, properties and interactions by nmr spectroscopy

    Author : Eric Morssing Vilén; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In this thesis the structure, properties and interactions of different types of carbohydrates were investigated by NMR spectroscopy. The structures of kappa- (κ) and kappa/mu- (κ/μ) carrageenan oligosaccharides were analyzed by studying the hydroxy protons. READ MORE

    Abstract : Rheumatoid arthritis (RA) is an autoimmune inflammatory disease that leads to degradation of cartilage and bone mainly in peripheral joints. In collagen-induced arthritis (CIA), a mouse model for RA, activation of autoimmune CD4+ T cells depends on a molecular recognition system where T-cell receptors (TCRs) recognize a complex between the class II MHC Aq protein and CII259-273, a glycopeptide epitope from type II collagen (CII).
