  2. 16. Structural and interaction studies of polysaccharides by NMR spectroscopy

    Author : Lena Lundqvist; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In this thesis, polysaccharides of different origins have been investigated by NMR spectroscopy with regard to structures and interactions. In paper I, hydrogen bonding interactions in kappa- (κ) and kappa/mu- (κ/μ) hybrid carrageenan oligosaccharides were studied by NMR spectroscopy of hydroxy protons. READ MORE

  4. 17. NMR spectroscopy in structural and conformational analysis of bacterial polysaccharides

    Author : Carolina Fontana; Göran Widmalm; Sven Müller-Loennies; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear Magnetic Resonance; carbohydrates; O-antigen polysaccharide; organisk kemi; Organic Chemistry;

    Abstract : Carbohydrates constitute one of the three major classes of biomolecules found in all living cells and, unlike nucleic acids and proteins, their polymeric structures are not based on a template. The structural diversity of these molecules confers them an enormous capacity to encode information in biological systems, acting as efficient mediators in the interaction of the cell with the environment.
