  1. 1. Macromolecules at Interfaces

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Helén Larsericsdotter; Uppsala universitet.; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Protein; Adsorption; Immobilization; Surface; Surface Plasmon Resonance; SPR; Mass Spectrometry; MS; Differential Scanning Calorimetry; DSC; FT ICR; Lysozyme; Bovine Serum Albumin; BSA; Myoglobin; Globular; Kemi; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi;

    Sammanfattning : In this thesis, the structure and stability of globular proteins adsorbed onto nanometer-sized hydrophilic silica particles were investigated using differential scanning calorimetry (DSC), hydrogen/deuterium exchange (HDX), and mass spectrometry (MS). The adsorption process itself was characterized with fluorescence and absorption spectroscopy and surface plasmon resonance (SPR). LÄS MER

    Sammanfattning : Mucus, an adherent hydrated layer covering the epithelium, is found in all internal tracts of the body and plays an important role in animal and human life. One of the essential functions of mucus is protection of tissues against dehydration. LÄS MER

  4. 4. Amylopectin - Interactions with Lipids and Proteins

    Detta är en avhandling från Food Technology, Lund University

    Författare :Henrik Lundqvist; Lund University.; Lunds universitet.; [2001]
    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. 5. Biological membrane interfaces involved in diseases a biophysical study

    Detta är en avhandling från Umeå : Kemi

    Författare :Fredrick Lindström; Umeå universitet.; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Solid-state NMR; DSC; Amyloid-beta peptide; Nociceptin; DMPC; DMPG; DDAB; peptide-lipid interaction; branched-chain fatty acid.; NATURAL SCIENCES Chemistry Physical chemistry Biophysical chemistry; NATURVETENSKAP Kemi Fysikalisk kemi Biofysikalisk kemi;

    Sammanfattning : Interactions between peptides and biological lipid membranes play a crucial role in many cellular processes such as in the mechanism behind Alzheimer’s disease where amyloid-beta peptide (Abeta)is thought to be a key component. The initial step of binding between a surface active peptide and its target membrane or membrane receptor can involve a non specific electrostatic association where positively charged amino acid residues and a negatively charged membrane surface interact.
