Konformationsanalyse von Pyranosen mit 13C-Resonanz

CHIMIA, 1971
The utility of 13C-NMR spectroscopy as a tool for conformational analysis in carbohydrate chemistry is described. The 13C atoms of axially oriented methoxy groups of methylglycosides absorb 1.5 to 2 ppm towards higher field than the equatorially ...

Defining the recognition elements of Lewis Y-reactive antibodies. [PDF]

PLoS ONE, 2014
Antibody response to carbohydrate antigens is often independent of T cells and the process of affinity/specificity improvement is considered strictly dependent on the germinal centers. Antibodies induced during a T cell-independent type 2 (TI-2) response
