The novel monosaccharide 8-amino-3,8-dideoxyoct-2-ulosonic acid (Kdo8N) was isolated by methanolysis from the lipooligosaccharide of the marine Gram-negative bacterium Shewanella pacifica. After HPLC purification, the absolute configuration was determined by the Mosher ester method and proven to be 4 R,5 R,6 R,7 R. This established the d- manno- configuration of the monosaccharide.
通过甲醇解从海洋革兰氏阴性细菌太平洋希瓦氏菌的脂寡糖中分离出新型单糖8-氨基-3,8-二脱氧辛-2-酮糖酸（Kdo8N）。经高效液相色谱纯化后，采用莫舍尔酯法确定其绝对构型，结果证明为4R、5R、6R、7R。由此确定了该单糖的d-甘露糖构型。
