An acidic polysaccharide from Alteromonas macleodii 2MM6 is shown to consist of tetrasaccharide repeating units containing D-galactose, 3-O-acetyl-2-acetamido-2-deoxy-D-glucose, 2-acetamido-2-deoxy-L-guluronic acid and 3,6-dideoxy-3-(4-hydroxybutyramido)-D-galactose residues. On the basis of sugar analysis, 1H and 13C NMR-spectroscopy data including NOE and one-dimensional HOHAHA experiments, the following structure was suggested for the polysaccharide repeating unit: [formula: see text] R: -CO-CH2-CH2-CH2-OH.
已证明来自麦克劳德交替单胞菌2MM6的一种酸性多糖由含有D-半乳糖、3-O-乙酰基-2-乙酰氨基-2-脱氧-D-葡萄糖、2-乙酰氨基-2-脱氧-L-古洛糖醛酸和3,6-二脱氧-3-(4-羟基丁酰胺基)-D-半乳糖残基的四糖重复单元组成。基于糖分析、包括NOE和一维全同核Hartmann-Hahn实验（HOHAHA实验）的1H和13C NMR光谱数据，推测该多糖重复单元具有以下结构：[分子式：见原文] R：-CO-CH2-CH2-CH2-OH。
