    Sammanfattning : In this thesis, bio-nanocomposites made from two alternative biopolymers and montmorillonite (Mnt) clay have been investigated by molecular modelling. These biopolymers are xyloglucan (XG) and chitosan (CHS), both of which are abundant, renewable, and cost-effective. LÄS MER

  2. 2. Foreign molecules in biomembranes : Molecular effects on intact stratum corneum and model lipid systems

    Detta är en avhandling från Division of Physical Chemistry, Faculty of Science, Lund University

    Författare :Quoc Dat Pham; [2016-08]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; stratum corneum; lipid; keratin filament; protein; DMPC; penetration enhancer; osmolyte; solvent; monoterpene; fatty acid; hydration; molecular mobility; fluidity; permeability; PT ssNMR; diffusion cell;

    Sammanfattning : This thesis mainly explores how the molecular mobility of lipid and protein components in the outermost layer of the skin, the stratum corneum (SC), varies with different conditions and upon adding foreign compounds. These studies require methods that makes it possible to detect and characterize the minor amount of fluid components in the highly ordered solid SC sample with resolved molecular information.

    Sammanfattning : This Thesis presents studies of molecular association in aqueous solution and at the liquid/solid interface. The investigated molecular systems range from self-aggregating surfactants to hydration water in contact with micelles or individual molecules. In most studies, combinations of various NMR methods were applied. LÄS MER

  5. 5. Molecular recognition and dynamics in proteins studied by NMR

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Chemical exchange; Conformational entropy; Entropy; Galectin-3; Isothermal Titration Calorimetry; ITC; Model-free formalism; Molecular recognition; Nuclear Magnetic Resonance; NMR; PGB1; Protein dynamics; Protein–ligand interactions; Proton-transfer reactions; Spin relaxation; Viscosity; Chemical exchange; Conformational entropy; Entropy; Galectin-3; Isothermal Titration Calorimetry; ITC; Model-free formalism; Molecular recognition; Nuclear Magnetic Resonance; NMR; PGB1; Protein dynamics; Protein–ligand interactions; Proton-transfer reactions; Spin relaxation; Viscosity;

    Sammanfattning : Knowledge of dynamics in protein is very important in the description of protein function and molecular recognition. The thesis investigates protein dynamics on time-scales from milli- to sub-nanosecond, with focus on the latter, using NMR spin relaxation experiments on two proteins, the 138-residue carbohydrate recognition domain of galectin-3 (Gal3C) and the 56-residue B1 domain of bacterial protein G (PGB1).
