    Sammanfattning : Owing to their key role in mucosal functioning as surface barriers with biospecific interaction potentials, the mucins are interesting candidates for use as surface modifiers in biomaterials applications. In this work, “mild” fractionation procedures were used to prepare mucins of bovine (BSM), porcine (PGM), and human (MG1) origin. LÄS MER

  3. 2. Enzyme Hydrolysis of Cellulose Derivatives. Active Site Studies and Polymer Characterisation

    Författare :Herje Schagerlöf; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry; Humicola insolens; Trichoderma reesei; Bacillus agaradhaerens; Mass spectrometry; Substituent distribution; Characterisation; Endoglucanases; Cellulose derivatives;

    Sammanfattning : Soluble derivatives of cellulose have become increasingly important in industrial products e.g. in pharmaceutical applications and in technical dispersions. The polymer characteristics of modified celluloses are to a high degree determined by the substituent distribution along the polymeric backbone. LÄS MER

  4. 3. New Methods for Enzyme Hydrolysis, Analysis, and Characterization of Modified Cellulose

    Författare :Claes Melander; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytisk kemi; Analytical chemistry; Methyl Cellulose; Reducing End; Micro Immobilised Enzyme Reactor; Mass Spectrometry; Enzyme Hydrolysis; Modified Cellulose; Substituent Distribution;

    Sammanfattning : Cellulose can be chemically modified to produce derivatives with specific properties. Knowledge of correlations between the modification reaction, substituent distribution, origin of cellulose and properties are importaint in order to design processess so as to produce derivatives with the desired properties.
