2. 1. Molecular Recognition Studies Based on Imprinting Technology

   Author : Cong Yu; Tillämpad biokemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; imprinting; molecular recognition; polymer; chiral separation; acrylamide; chromatography; functional monomer; cross-linking; hydrogen bonding; hydrophobic interactions; aqueous media; solvent; antibody; mimics; receptor; artificial enzyme; Bioteknik; Biotechnology; Biokemi; Metabolism; Biochemistry;

   Abstract : In this thesis, I have focused on five main research areas: 1). A new type of imprinted polymer has been developed, namely the amide MIP. The amide functional monomers showed better hydrogen bonding capabilities in polar organic solvents and the resulting polymers exhibited good enantiomeric recognition properties in organic media.

4. 2. Ligand binding and enzyme catalysis studied by molecular dynamics simulations

   Author : Tomas Hansson; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; molecular dynamics simulation; free energy; linear response; drug design; empirical valence bond; HIV protease; protein tyrosine phosphatase; Molekylärbiologi; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

   Abstract : Molecular dynamics simulations and free energy calculations can be applied to biomolecular systems to predict ligand binding affinities. Combined with hybrid quantum-classical potential energy surfaces, such computations can also be used to probe enzymatic catalysis mechanisms. READ MORE

5. 3. Exploring Molecular Interactions : Synthesis and Studies of Clip-Shaped Molecular Hosts

   Author : Anjaneya Prasad Polavarapu; Helena Grennberg; Adolf Gogoll; Jerker Mårtensson; Uppsala universitet; []
   Keywords : Organic chemistry; Glycoluril clips; host-guest systems; supramolecular chemistry; complexation induced shifts; conformational restriction; NMR spectroscopy; fullerene binding; Organisk kemi;

   Abstract : Molecular recognition via noncovalent interactions plays a key role in many biological processes such as antigen-antibody interactions, protein folding, the bonding and catalytic transformation of substrates by enzymes, etc. Amongst these noncovalent interactions, electrostatic interactions, hydrogen bonding, π-π interactions, and metal-to-ligand bonding are the most prominent.

6. 4. Towards the Rational Design of Molecularly Imprinted Polymers

   Author : Håkan S Andersson; Ann-Christin Koch-Schmidt; Ian A Nicholls; Klaus Mosbach; Richard F Venn; Tillämpad biokemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Thermodynamics; Molecular Recognition; Polyvalency; Cooperativity; Electrostatic Interactions; Hydrophobic Effect; Chromatography; Frontal Analysis; HPLC; Spectroscopy; Molecularly Imprinted Polymer; Molecular Imprinting; Crown Ether; Template Polymerisation; Cyclodextrin; Biochemistry; Metabolism; Biokemi; Biotechnology; Bioteknik; molecular recognition; Biokemi;

   Abstract : Molecular imprinting is a technique by which polymeric materials selective for a given target molecule can be created through a casting procedure. Functionalised monomers are added to a solution of molecular templates. READ MORE

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

   Author : Quoc Dat Pham; Fysikalisk kemi; []
   Keywords : stratum corneum; lipid; keratin filament; protein; DMPC; penetration enhancer; osmolyte; solvent; monoterpene; fatty acid; hydration; molecular mobility; fluidity; permeability; PT ssNMR; diffusion cell;

   Abstract : 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.
