  1. 1. Glycoconjugates : synthesis and investigation of carbohydrate-protein interactions

    Författare :Sara Spjut; Mikael Elofsson; Ulf Ellervik; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Glycoconjugates; Carbohydrates; Galactose; Glucose; Solid-phase synthesis; SPOS; Glycosylation; Gel-phase 19F NMR spectroscopy; Fluorinated linker; Carbohydrate array; Microtiter plates; Carbohydrate-protein interactions; carbamate linker; Fsec; Protecting group; Fluorinated protecting group; Multivalent glycoconjugates; Adenovirus; Ad37; Epidemic keratoconjunctivitis; EKC; Sialic acid; Adenovirus inhibitor; Trivalent; Tetravalent; X-ray crystal structure; Bioorganic chemistry; Bioorganisk kemi; organisk kemi; Organic Chemistry;

    Sammanfattning : To study the functions of glycoconjugates in biological systems reliable and efficient protocols for glycoconjugate synthesis are needed. To reach this goal we have developed methods for solid-phase synthesis of glycoconjugates that can be monitored with gel-phase 19F spectroscopy using fluorinated linkers, building blocks, and protecting groups.

  3. 2. On the Course of Kraft Cooking - The impact of ionic strength

    Författare :Binh Dang; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; molecular weight distribution.; hexenuronic acids; carbohydrate removal; delignification; sodium ion concentration; lignin; ionic strength; xylan; flow-through kraft cooking; kinetics;

    Sammanfattning : Kraft pulping is the dominant process currently used to produce chemical pulps, and has been applied for more than 130 years. A large number of studies have been conducted to gain a better understanding of the delignification kinetics as well as the reactions of the wood components being dissolved during the cooking process.

  5. 4. Deepening the insights of lignin structure : Lignin-carbohydrate complex (LCC) fractionation and characterization and Kraft lignin amination

    Författare :Xueyu Du; Jiebing Li; Mikael Lindström; Jussi Sipilä; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Improvement of kraft pulping delignification efficiency and value-addition of industrial kraft lignin are two attractive topics. The proposal that delignification is deteriorated by the presence of lignin-carbohydrate complex (LCC) is still being debated. LÄS MER

  7. 5. Structural biology of carbohydrate transfer and modification in natural product biosynthesis

    Författare :Magnus Claesson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Certain organisms, can during periods of limited resources, adapt their metabolism to enable biosynthesis of secondary metabolites, compounds that increase competitiveness and chances of survival. The subjects of this thesis are enzymes acting on carbohydrate substrates during secondary metabolism. LÄS MER
