The exopolysaccharide produced by Lactobacillus helveticus 766 in skimmed milk was found to be composed of D-glucose and D-galactose in a molar ratio of 2:1. Linkage analysis and 1D/2D NMR studies (1H and 13C) performed on the native polysaccharide, and on oligosaccharides obtained from a partial acid hydrolysate, showed the polysaccharide to consist of hexasaccharide repeating units with the following structure: [formula: see text]
瑞士乳杆菌766在脱脂乳中产生的胞外多糖被发现由摩尔比为2:1的D-葡萄糖和D-半乳糖组成。对天然多糖以及从部分酸水解产物中获得的寡糖进行的连接分析和一维/二维核磁共振研究（氢谱和碳谱）表明，该多糖由具有以下结构的六糖重复单元组成：[化学式：见原文]
