  1. 1. Structure, dynamics and reactivity of carbohydrates NMR spectroscopic studies

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

    Författare :Jerk Rönnols; Stockholms universitet.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbohydrates; Conformation; NMR spectroscopy; Hydrogen bond; Organic Chemistry; organisk kemi;

    Sammanfattning : The main focus of this thesis is on the ring conformations of carbohydrate molecules; how the conformational equilibria and the rates of the associated interconversions are affected by the molecular constitution and their surroundings.The conformational equilibria of a group of amine linked pseudodisaccharides, designed as potential glycosidase inhibitors, comprising α-D-altrosides are described in Chapter 3.

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NMR specroscopy; MD simulations; carbohydrates; NATURAL SCIENCES Chemistry Organic chemistry; NATURVETENSKAP Kemi Organisk kemi; organisk kemi; Organic Chemistry;

    Sammanfattning : Knowledge about the structure, conformation and dynamics of carbohydrates is important in our understanding of the way carbohydrates function in biological systems, for example in intermolecular signaling and recognition. This thesis is a summary of five papers studying these properties in carbohydrate-containing molecules with NMR spectroscopy and molecular dynamics simulations. LÄS MER

  3. 3. Synthesis and analysis of carbohydrates related to bacterial polysaccharides

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

    Författare :Hani Mobarak; Stockholms universitet.; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; carbohydrates; synthesis; conformation; NMR; O-antigen; computer-assisted structure elucidation; Organic Chemistry; organisk kemi;

    Sammanfattning : The outer surface of bacteria is composed of around 75% carbohydrates, which are vital for the bacteria to survive and communicate with the host biological system. The thesis discusses different properties of carbohydrates that are essential for understanding the bacterial behavior in biological systems. LÄS MER

  4. 4. Exploring the Molecular Behavior of Carbohydrates by NMR Spectroscopy Shapes, motions and interactions

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

    Författare :Olof Engström; Stockholms universitet.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NMR spectroscopy; NMR relaxation; DNMR; CORCEMA-ST; carbohydrates; caffeine; O-antigen; glycofullerenes; Organic Chemistry; organisk kemi;

    Sammanfattning : Carbohydrates are essential biomolecules that decorate cell membranes and proteins in organisms. They are important both as structural elements and as identification markers. Many biological and pathogenic processes rely on the identification of carbohydrates by proteins, thereby making them attractive as molecular blueprints for drugs. LÄS MER
