1. Enthalpy and Entropy in Enzyme Catalysis : A Study of Lipase Enantioselectivity
Sammanfattning : Biocatalysis has become a popular technique in organic synthesis due to high activity and selectivity of enzyme catalyzed reactions. Enantioselectivity is a particularly attractive enzyme property, which is utilized for the production of enantiopure substances. LÄS MER
2. Influence of immobilisation and reaction conditions on lipase enantioselectivity : resolution of alkyl substituted carboxylic acids and primary alcohols
Sammanfattning : .... LÄS MER
3. Enantiomeric Separations using Chiral Counter-Ions
Sammanfattning : This thesis describes the use of chiral counter-ions for the enantiomeric separation of amines in non-aqueous capillary electrophoresis. The investigations have been concentrated on studies of the influence, of the chiral counter-ion, the solvent, the electrolyte and the analyte, on the enantioselective separation. LÄS MER
4. Biochemical Studies on a Plant Epoxide Hydrolase : Discovery of a Proton Entry and Exit Pathway and the Use of In vitro Evolution to Shift Enantioselectivity
Sammanfattning : The work leading to this thesis has provided additional information and novel knowledge concerning structure-function relationship in the potato epoxide hydrolase. Epoxide hydrolases are enzymes catalyzing the hydrolysis of epoxides to yield the corresponding vicinal diols. LÄS MER
5. The influence of temperature on enzyme selectivity in organic media
Sammanfattning : The influence of different reaction parameters on enzyme selectivity was investigated. The reaction conditions studied were solvent dependence, water activity and reaction temperature. LÄS MER
