  2. 21. Selectivity in Host-Guest Chemistry

    Author : Gunnar Westman; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis describes host-guest complexes with the use of a biphenyl crown ether or cyclodextrin as host. Complexes between the biphenyl crown ether and salts form phenylalanine esters were studied. READ MORE

  4. 22. Conformational Dynamics of Carbohydrates Studied by NMR Spectroscopy and Molecular Simulations

    Author : Jennie Östervall; Göran Widmalm; C. Allen Bush; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Carbohydrates; NMR; Molecular Dynamics; Conformation; Dynamics; Residual Dipolar Couplings; Cyclodextrins; Oligosaccharides; Organic chemistry; Organisk kemi;

    Abstract : Carbohydrates play important roles in biological processes. Their function is closely related to their conformation. In this thesis, conformational studies of carbohydrates by NMR spectroscopy and molecular dynamics computer simulations are described. READ MORE

  5. 23. On the Size and Shape of Polymers and Polymer Complexes : A Computational and Light Scattering Study

    Author : Tomas Edvinsson; Terence Cosgrove; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Monte Carlo simulations; grafted polymers; shape description; folding complexity; clustering; percolation algorithm; light scattering; end-capped polymers; inclusion complexes; Fysik; Physics; Fysik; Physical Chemistry; Fysikalisk kemi;

    Abstract : Detailed characterization of size and shape of polymers, and development of methods to elucidate the mechanisms behind shape transitions are central issues in this thesis. In particular we characterize grafted polymer chains under confinement in terms of the chain entanglement complexity and mean molecular size. READ MORE

  6. 24. NMR studies of the amyloid beta-peptide

    Author : Jens Danielsson; Astrid Gräslund; Chris Dobson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NMR; amyloid beta peptide; structure; metal interaction; diffusion; Biophysics; Biofysik;

    Abstract : The Amyloid beta peptide (Ab) is related to Alzheimer’s disease and is suggested to be the molecular pathogenic species of the disease, probably through the neurotoxic effect of Ab oligomers. Here the results from biophysical studies of Ab and fragments thereof, are presented. READ MORE

  7. 25. New approaches to concentration, desalting and separation of biopolymers in capillary electrophoresis

    Author : Rong Zhang; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

    Abstract : In the first part of the thesis five new on-tube methods for concentration and desalting ofampholytes, such as peptides and proteins, are described in Papers I and II. The methods arebased on the fact that electrophoretic migration velocities decrease upon a decrease in theabsolute value of the zeta potential of a solute and the pore size of the electrophoresis mediumand upon an increase in the cross section of the electrophoresis chamber, the viscosity and theelectrical conductivity of the electrophoresis medium.
