3-Deoxy- d - manno -2-octulosonic acid (KDO), a sugar previously presumed to occur only as a glycosyl residue in polysaccharides produced by Gram-negative bacteria, was found to be a component of the cell walls of higher plants. In the form of the disaccharide α- l -Rha p -(1→5)- d -KDO, KDO was released by mild hydrolysis with acid from the purified cell wall polysaccharide rhamnogalacturonan II. KDO was
摘要3-脱氧-d-甘露糖-2-辛酸(KDO)是一种高等植物细胞壁的成分,这种糖以前被认为仅作为革兰氏阴性细菌产生的多糖中的糖基残基存在。 。以二糖α-1-Rhap-(1→5)-d -KDO的形式,KDO通过用酸温和水解从纯化的细胞壁多糖鼠李糖半乳糖醛酸聚糖II中释放出来。已显示KDO存在于几种植物的纯化细胞壁中,包括双子叶植物,单子叶植物和裸子植物。在这项研究期间,开发了检测和定量多糖中KDO残留的改进方法。
