  1. 16. Enthalpy and Entropy in Enzyme Catalysis : A Study of Lipase Enantioselectivity

    Författare :Jenny Ottosson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biocatalysis; enzyme catalysis; Candida antarctica lipase B; enantioselectivity; enthalpy; entropy; CALB; enantiomeric ratio; Bioengineering; Bioteknik;

    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

  3. 17. Lipase catalysed synthesis of speciality chemicals: technical, economical & environmental aspects

    Författare :Pär Tufvesson; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Green Chemistry; surfactant; biocatalysis; enzymatic; epoxide;

    Sammanfattning : Most people agree that the total ecological impact of society has become more than this planet can endure. This is because we consume our resources (such as oil and water) faster than they can regenerate and because we release more substances into the environment than can be assimilated (e.g. CO2).

  4. 18. Mesostructured particulate silica materials with tunable pore size : Synthesis, characterization and applications

    Författare :Malin Helena Sörensen; Per Claesson; Viveka Alfredsson; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mesoporous materials; aersol-based process; emulsion-based process; biocatalysis; sustained release; 3D hexagonal; 2D hexagonal; powder; spherical particles; liquid crystalline phases; AFM-porosimetry; Pluronic; Chemistry; Kemi;

    Sammanfattning : Colloidal assemblies of surfactants and polymers in aqueous solutions have been used by human mankind for hundreds of years and they are of great importance in many of our technological processes, such as fabrication of soap and papermaking. Less than two decades ago the idea of using colloidal assemblies as templates of inorganic materials was borne. LÄS MER

  5. 19. Sequence- and structure guided engineering of proteins and enzymes for biotechnology and health applications

    Författare :Karen Schriever; Per-Olof Syrén; Elton P. Hudson; Eric A. Gaucher; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; protein engineering; enzymology; ancestral sequence reconstruction; antigen engineering; structural biology; terpene cyclases; enzyme thermodynamics; biocatalysis; phosphatases; allosteric regulation; Biotechnology; Bioteknologi;

    Sammanfattning : Proteins are highly diverse and sophisticated biomolecules that represent a cornerstone of biological structure and function and have been exploited in man-made applications for thousands of years. Those proteins that facilitate chemical reactions at physiologically relevant time-scales are referred to as enzymes. LÄS MER

  7. 20. Extending the Reach of Computational Approaches to Model Enzyme Catalysis

    Författare :Beat Anton Amrein; Shina Caroline Lynn Kamerlin; Adrian Mulholland; Uppsala universitet; []
