Abstract
Complete assignments for the 1H- and the 13C-NMR spectra of the O-specific polysaccharide of S. sonnei/Plesiomonas shigelloides are reported. Evidence is presented that in this polysaccharide both pyranose residues exist preferentially in the 4C1 chair conformation and that the polysaccharide exists in the zwitterion form.
摘要
报道了宋内志贺菌/类志贺邻单胞菌O-特异性多糖的1H-和13C-NMR光谱的完整任务。有证据表明，在这种多糖中，两个吡喃糖残基优先以4C1椅式构象存在，并且该多糖以两性离子形式存在。
