  1. 1. Metabolites of Avena sativa with Blood Cholesterol Lowering Properties

    Author : Narda Thuresson; Centrum för analys och syntes; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cholesterol lowering effect; Avena sativa; phytosterols; avenanthramides; 13-HODE;

    Abstract : Cardiovascular diseases are among the most important causes of death in thedeveloped countries. These diseases are partly caused by too high cholesterolconcentrations in the blood. Avena sativa, oat, is the most common spieces of the genus Avena, and produced in huge amounts worldwide. READ MORE

  2. 2. Design, Synthesis and Thermodynamic Studies of Galectin Ligands

    Author : Maria Luisa Verteramo; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; galectin; conformational entropy; solvation; thermodynamic; interaction; molecular recognition; thiodigalactoside; diastereomer; structure-based design;

    Abstract : The signaling within and between cells in biology is governed by molecular recognition between natural or synthetic ligands and proteins. This thesis project aimed to investigate the thermodynamic properties of specific interaction between synthetic ligands and galectin proteins. READ MORE

  4. 4. Development of Simultaneous Saccharification and Fermentation for Production of Ethanol from Softwood

    Author : Malek Alkasrawi; Centrum för analys och syntes; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; Kemiteknik och kemisk teknologi; spruce; softwood; fermentation; cultivation; Tween-20; SSF; recirculation; Ethanol production; process streams;

    Abstract : This thesis deals with the development of simultaneous saccharification and fermentation (SSF) in order to improve the economy of the softwood-to-ethanol process. The effect of process stream recirculation on ethanol production from steam-pretreated softwood based on SSF was investigated for two process cases. READ MORE
