  2. 6. Protein-Surfactant Interactions Phase Behaviour and Phase Structure

    Author : Anna Karin Morén; Fysikalisk kemi; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 7. Protein-Polymer Interaction and Association in Aqueous Solution

    Author : Malin Jönsson; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Fysikalisk kemi; Makromolekylär kemi; Macromolecular chemistry; enzymologi; Proteiner; enzymology; Proteins; Aqueous two-phase systems; Monte Carlo Simulations; hydrophobic effect; surface hydrophobicity; plasmid DNA; Protein; polymer;

    Abstract : The aim of this thesis has been to study protein-polymer interaction and association. Two different techniques were used; Monte Carlo simulations were combined with partitioning in polymeric aqueous two-phase systems. Monte Carlo simulations have been used to evaluate the hydrophobic interaction in electrolyte solution. READ MORE

  5. 8. Fouling and cleaning of solid surfaces. The influence of surface characteristics and operating conditions

    Author : Camilla Karlsson; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; ellipsometry; sodium hydroxide; anionic surfactant; betalactoglobulin; protein; stainless steel; hydrophilic surface; hydrophobic surface; cleaning; adsorption; fouling; Livsmedelsteknik; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Abstract : The severe fouling common in food processing puts high demands on equipment cleaning. Adsorption of the protein betalactoglobulin to solid surfaces and its subsequent removal were followed using in situ ellipsometry. Most experiments were done in a stirred cuvette. Additionally, a flow cell was designed, which was employed in some work. READ MORE

  6. 9. Amylopectin - Interactions with Lipids and Proteins

    Author : Henrik Lundqvist; Livsmedelsteknik; []
    Keywords : 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;

    Abstract : 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. 10. Drug Partitioning into Natural and Artificial Membranes : Data Applicable in Predictions of Drug Absorption

    Author : Caroline Engvall; Birgitta Tomkinson; Katarina Edwards; Sven Engström; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Bilayer disk; Cholesterol; Drug partitioning; Drugs; Electrostatic effects; Immobilized liposome chromatography; Liposome; Membrane protein; Model membrane; Oligonucleotide-liposome complex; Phospholipid; Phospholipid bilayer; Proteoliposome; Surfactant; Biokemi; Biochemistry; Biokemi;

    Abstract : When drug molecules are passively absorbed through the cell membrane in the small intestine, the first key step is partitioning of the drug into the membrane. Partition data can therefore be used to predict drug absorption. READ MORE
