The structure of a new acidic sugar from the extracellular polysaccharide of Butyrivibrio fibrisolvens strain 49 was determined as 4-O-(1-carboxyethyl)-D-galactose on the basis of 13C-n.m.r. and 1H-n.m.r. spectroscopy, m.s. and chemical degradation studies.
基于碳-13核磁共振、氢-1核磁共振光谱、质谱及化学降解研究,确定了来自溶纤维丁酸弧菌49株胞外多糖的一种新酸性糖的结构为4-O-(1-羧乙基)-D-半乳糖。
