    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

    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

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

    Detta är en avhandling från Stockholm : Department of Organic Chemistry, Stockholm University

    Författare :Robert Pendrill; Stockholms universitet.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbohydrates; Oligosaccharide; Conformation; NMR spectroscopy; MD simulations; Organic Chemistry; organisk kemi;

    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.
