    Sammanfattning : Oligosaccharides (carbohydrates) are a large class of biological molecules that are important as energy sources in the human body and have enormously varied biological functions. It is generally believed that biological activities of carbohydrates are related to their internal dynamics. LÄS MER

  4. 3. Design and synthesis of xyloglucan oligosaccharides : structure-function studies and application of xyloglucan endotransglycosylase PttXET16A

    Författare :Martin J. Baumann; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; xyloglucan oligosaccharides; xyloglucan endotransglycosylase; XET; crystal structure; fiber surface modification; Populus tremula x Populus tremuloides; Hybrid aspen;

    Sammanfattning : Primary cell walls are a composite of cellulose microfibrilsand hemicelluloses. Xyloglucan is the principal hemicelluloseof primary cell walls of dicotyledons. Xyloglucanendotransglycosylases (XETs) cleave and religate xyloglucanpolymers in plant cell walls. LÄS MER

  5. 4. Conformations of Flexible Oligosaccharides : Molecular Simulations and NMR spectroscopy

    Författare :Robert Pendrill; Göran Widmalm; Jens Duus; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbohydrates; Oligosaccharide; Conformation; NMR spectroscopy; MD simulations; organisk kemi; Organic Chemistry;

    Sammanfattning : The conformational preferences of several oligosaccharides are investigated herein using a combination of NMR spectroscopy and molecular dynamics (MD) simulations, focusing on the torsion angles associated with the glycosidic linkages.Strategies for obtaining usable J-HMBC spectra for carbons with an adjacent 13C label are described.
