Two distinct forms of the O6 antigen (LPS) from E. coli were analysed using 1H and 13C NMR spectroscopy. Their structures were found to be [formula: see text] In the O6-specific polysaccharide from E. coli O6:K2 and O6:K13, X is beta-D-Glc p, as had previously been shown for the O6 polysaccharide from E. coli O6:K15; in the O6 specific polysaccharide from E. coli O6:K54, X is beta-D-Glc pNAc.
利用1H和13C核磁共振光谱分析了来自大肠杆菌的两种不同形式的O6抗原（脂多糖）。发现它们的结构为[化学式：见正文]。在大肠杆菌O6:K2和O6:K13的O6特异性多糖中，X为β-D-葡萄糖吡喃糖，正如之前对大肠杆菌O6:K15的O6多糖所显示的那样；在大肠杆菌O6:K54的O6特异性多糖中，X为β-D-葡萄糖吡喃糖胺。
