    Sammanfattning : The first chapter of this thesis describes glycosylation strategies for obtaining derivatives of 2-amino-2-deoxy-a-D-glucopyranosyl-(1-->6)-D-myo-inositol, a key building block for synthesis of glycosylphosphatidylinositol anchor substances and also proposed to be part of a second messenger for insulin.The second chapter describes the synthesis of bifunctional oligoethylene glycol spacers and glycosylation of these for use in formation of glycoconjugates.

    Sammanfattning : Covalent bonds between lignin and carbohydrates, forming a matrix referred to as lignin carbohydrate complexes (LCC), remain one of the most controversial topics in wood chemistry. A key issue is whether they are formed during chemical and mechanical pretreatments of the compact wood structure or actually present in wood prior to isolation. LÄS MER
