Abstract

The polysaccharide moiety of the O22-antigen (lipopolysaccharide, LPS) consists of 2-acetamido-2-deoxy-D-galactose, D-glucuronic acid, D-glucose, and D-galactose in the molar ratios 2:1:1:1. Methylation analysis as well as 1D and 2D NMR spectroscopy showed that the O22 polysaccharide has the primary structure [formula: see text]

摘要

O22抗原（脂多糖，LPS）的多糖部分由2-乙酰氨基-2-脱氧-D-半乳糖、D-葡萄糖醛酸、D-葡萄糖和D-半乳糖组成，摩尔比为2:1:1:1。甲基化分析以及一维和二维核磁共振光谱表明，O22多糖具有一级结构[分子式：见原文]
