Abstract
The lipopolysaccharide from Pseudomonas aeruginosa O12 (Lányi classification) gave on mild acid hydrolysis an O-specific polysaccharide built of D-ribose and N-acetyl-D-galactosamine. The disaccharide structure----4)-alpha-GalNAcp-(1----2)-beta-Ribf-(1----for the repeating unit of the polysaccharide was established by nondestructive way involving full interpretation of its 1H- and 13C-NMR-spectra, using homonuclear and selective heteronuclear 13C[1H] double resonances.
摘要
铜绿假单胞菌O12（兰伊分类）的脂多糖经温和酸水解后产生一种由D-核糖和N-乙酰-D-半乳糖胺构成的O-特异性多糖。通过对其1H-和13C-NMR光谱进行全面解析，并利用同核和选择性异核13C[1H]双共振的无损方法，确定了该多糖重复单元的二糖结构----4)-α-GalNAcp-(1----2)-β-Ribf-(1---- 。
