The Pseudomonas holci 8300 lipopolysaccharide has an O-specific polysaccharide chain, containing L-rhamnose and 3-acetamido-3-deoxy-D-fucose residues in the ratio 4:1. On the basis of methylation, Smith degradation, and 1H- and 13C-NMR spectroscopy data, it was concluded that the polysaccharide is built up of pentasaccharide units of A and B types in the ratio approximately 2.5:1. In some stretches of the polysaccharide, minor B units form rather long chains, and in the others they alternate with predominant A units. (formula; see text)
假单胞菌8300脂多糖具有一条O-特异性多糖链，其含有比例为4:1的L-鼠李糖和3-乙酰氨基-3-脱氧-D-岩藻糖残基。基于甲基化、史密斯降解以及1H-和13C-核磁共振光谱数据，得出该多糖由比例约为2.5:1的A、B型五糖单元构成。在多糖的某些片段中，少量的B单元形成相当长的链，而在其他片段中，它们与占主导的A单元交替出现。（化学式；见正文）
