  1. 1. Protein-surfactant interactions

    Författare :Ank Valstar; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik; Physical Chemistry; fysikalisk kemi;

    Sammanfattning : Protein-surfactant interactions in aqueous media have been investigated. The globular proteins lysozyme and bovine serum albumin (BSA) served as model proteins. Several ionic and non-ionic surfactants were used.Fluorescence probe measurements showed that at low sodium dodecyl sulfate (SDS) concentration (< 0. LÄS MER

  3. 2. Association and Interactions in Protein-Surfactant Systems

    Författare :Anna Stenstam; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; catanionic surfactant; SANS; NMR; gel; sodium alkylsulfate; Protein-surfactant interactions; lysozyme; LH2; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : Aggregation in protein-surfactant systems have been studied with the ambition of reaching a deeper understanding of the balance of the interaction forces involved. A pure system with maximized electrostatic interactions has been used. LÄS MER

  4. 3. Protein-Surfactant Interactions Phase Behaviour and Phase Structure

    Författare :Anna Karin Morén; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Phase equilibria; Protein-surfactant interactions; Gel; Precipitate; Solution; Lysozyme; b-lactoglobulin; Ovalbumin; Bovine serum albumin; Dodecyltrimethylammonium chloride; Sodium alkylsulphates; NMR; Cryo-TEM; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : Protein-surfactant interactions in water are investigated by following the phase equilibria for protein-surfactant pairs whose constituents carry both opposite and the same sign of charge. The concentration ranges studied are: 0-20 wt% protein, 0-20 wt% surfactant, and 80-100 wt% water. LÄS MER

  5. 4. Dynamics of Enzymes at Interfaces : Lipase adsorption and mobility on solid surfaces

    Författare :Andreas Sonesson; Hjalmar Brismar; Robert Tilton; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biophysics; surface chemistry; diffusion; enzymes; lipases; adsorption; mobility; Physics; Fysik;

    Sammanfattning : This thesis aimed to give more insight in the dynamics of enzymes at interfaces. The adsorption and mobility of adsorbed proteins can e.g. give a better understanding of structure-function properties of interfacially active enzymes. LÄS MER
