  1. 1. Biomass-derived nanoscopic catalysts for water treatment : Structure-property relationship investigation

    Författare :Jianhong Chen; Adam Slabon; Germán Salazar Alvarez; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; green chemistry; water purification; electrochemistry; photochemistry; biomass material; structure-property relationship; oorganisk kemi; Inorganic Chemistry;

    Sammanfattning : Green Chemistry has received widespread interest due to its capacity to meet environmental and economic objectives. The Twelve Principles were proposed to better perform Green Chemistry and have become the guideline for solving many environmental issues. Water contamination has become a major global challenge in the 21st century. LÄS MER

  3. 2. Deciphering Carbohydrate Structure : From NMR Chemical Shifts to Conformational Analysis

    Författare :Kevin M. Dorst; Göran Widmalm; Martina Delbianco; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NMR chemical shift prediction; Structural elucidation; Conformational studies; NMR spectroscopy; MD simulations; Organic Chemistry; organisk kemi;

    Sammanfattning : Carbohydrates are ubiquitous in nature and exhibit a multitude of roles. Besides nucleic and amino acids, they can be regarded as the third alphabet of life. They are used as energy source to fuel the cells, as structural building blocks and play a key role in cellular recognition processes. LÄS MER

  4. 3. Towards Mosquitocides for Prevention of Vector-Borne Infectious Diseases : discovery and Development of Acetylcholinesterase 1 Inhibitors

    Författare :Sofie Knutsson; Anna Linusson; Fredrik Almqvist; Andreas Larsson; Ulf Nilsson; Umeå universitet; []

    Sammanfattning : Diseases such as malaria and dengue impose great economic burdens and are a serious threat to public health, with young children being among the worst affected. These diseases are transmitted by mosquitoes, also called disease vectors, which are able to transmit both parasitic and viral infections. LÄS MER

  5. 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

    Författare :Ann Gurell; Mikael Widersten; Bengt Mannervik; Dick Janssen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; epoxide hydrolase; enantioselectivity; in vitro evolution; proton wire; epoxides; selectivity; CASTing; structure-function; Biochemistry; Biokemi; Biokemi; Biochemistry;

    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

  7. 5. Exploring Selectivity and Hysteresis : Kinetic Studies on a Potato Epoxide Hydrolase

    Författare :Diana Lindberg; Mikael Widersten; Gunnar Johansson; Richard N. Armstrong; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Epoxide hydrolase; regioselectivity; selectivity; hysteresis; conformational changes; cooperativity; deep eutectic solvents; methylstyrene oxide; Biochemistry; Biokemi; Biokemi; Biochemistry;

    Sammanfattning : The kinetic mechanism of an α/β hydrolase fold epoxide hydrolase from potato, StEH1, has been studied with the aims of explaining the underlying causes for enantio- and regioselectivity, both being important for product purity. Further effort has been laid upon understanding the causes of a hysteretic behavior discovered in the measurements leading to Paper I. LÄS MER
