  2. 16. Probing Paramagnetic Systems by Solid-State NMR Spectroscopy

    Author : José P. Carvalho; Andrew J. Pell; Sharon Ashbrook; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Solid-state NMR; Magic-Angle Spinning; Paramagnetic NMR; Frequency-Swept Adiabatic Pulses; Quantum Chemistry; Quadrupolar Interaction; Physical Chemistry; fysikalisk kemi;

    Abstract : Paramagnetic systems have a wide range of applications ranging from energy storage or conversion to catalytic processes, metalloproteins and light-emitting materials. Over the recent years nuclear magnetic resonance (NMR) spectroscopy has become an established tool for studying the structural and electronic properties of these systems, largely because it can provide a link between the structure and the bulk properties.

  4. 17. Structural and Interaction Studies of Bacterial Polysaccharides by NMR Spectroscopy

    Author : Eva-Lisa Nordmark; Göran Widmalm; Sven Müller-Loennies; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bacterial polysaccharides; NMR; interaction studies; structural studies; Escherichia coli; Salmonella enteritidis; Streptococcus thermophilus; Propionibacterium freudenreichii; Pseudoalteromonas aliena; P22 TSP; Organic chemistry; Organisk kemi;

    Abstract : An introduction to bacterial polysaccharides and the methods for structural determination are described in the first two parts of the thesis.In a structural elucidation of bacterial polysaccharides NMR experiments are important as is component analysis. A short description of immunochemical methods such as enzyme immunoassays is included. READ MORE

  5. 18. The Application of isotropic bicelles as model membranes

    Author : August Andersson; Lena Mäler; G Arthur III Palmer; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bicelle; membrane; peptide; spectroscopy; NMR; Molecular biophysics; Molekylär biofysik;

    Abstract : Isotropic bicelles are disc-shaped aggregates of lipids and detergents, and are suitable model systems for high-resolution NMR studies of membrane-interacting peptides. In this thesis the structures for the two peptides motilin and transportan were determined by homonuclear 1H methods in the presence of bicelles, and the structure of the bovine prion protein peptide (bPrPp) was solved in the presence of DHPC micelles.

  6. 19. Structure Elucidations of Bacterial Polysaccharides using NMR Spectroscopy and Bioinformatics

    Author : Jonas Ståhle; Göran Widmalm; Evgeny Vinogradov; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Carbohydrates; Bioinformatics; NMR Spectroscopy; Lipopolysaccharide; Glycosyltransferase; Computer-Assisted Structure Elucidation; O-antigen; Biosynthesis; Organic Chemistry; organisk kemi;

    Abstract : Carbohydrates are ubiquitous components in nature involved in a range of tasks. They cover every cell and contribute both structural stability as well as identity. Lipopolysaccharides are the outermost exposed part of the bacterial cell wall and the primary target for host-pathogen recognition. READ MORE

  7. 20. NMR Studies of Inclusion Compounds

    Author : Sahar Nikkhou Aski; Jozef Kowalewski; Pierre Mutzenhardt; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NMR; 13C spin relaxation; PFGNMR; Kinetics; Correlation time; Physical chemistry; Fysikalisk kemi; Physical Chemistry; fysikalisk kemi;

    Abstract : This thesis presents the application of some of the NMR methods in studying host-guest complexes, mainly in solution. The general focus of the work is on investigating the reorientational dynamics of some small molecules that are bound inside cavities of larger moieties. READ MORE
