    Description / Table of Contents: Um eine Matrix zur Immobilisierung von Enzymen herzustellen, wurden Alginsäure, ein natürlich vorkommendes Polysaccharid, als Rückgrat und Glycidylmethacrylat (GMA) und 2-Hydroxyethylmethacrylat (HEMA) als Monomere für die Pfropfcopolymerisation gewählt. HEMA wurde verwendet, um den hydrophilen Charakter, der durch die Einführung von GMA verlorenginge, zu erhalten. Die Immobilisierung von Trypsin geschieht durch kovalente Bindung an die Matrix. Die optimale Temperatur beträgt für das immobilisierte Enzym 35°C, und es ist bei pH 8 am stabilsten.
    Notes: To synthesize a matrix for the immobilization of enzymes, alginic acid, a naturally occurring polysaccharide has been chosen as the backbone, and glycidyl methacrylate (GMA) and 2-hydroxy ethyl methacrylate (HEMA) as monomers for graft copolymerization. HEMA was used to introduce hydrophilic character which would have been lost during the introduction of the hydrophobic monomer glycidyl methacrylate into alginic acid. Immobilization of trypsin onto this matrix takes place by covalent bonding. The temperature optimum of the immobilized enzyme was found to be 35°C and it was most stable at pH 8.
