d -galactan-containing glycoproteins having a potent inhibitory activity against eel anti-H agglutinin were isolated from the hot saline extracts of mature radish leaves and characterized to have a similar monosaccharide composition that consists of l -arabinose, d -galactose, l -fucose, 4-O-methyl- d -glucuronic acid, and d -glucuronic acid residues. The chemical structure features of the carbohydrate
摘要从成熟萝卜叶的热盐水提取物中分离出了两种对鳗鱼抗H凝集素具有强抑制活性的含α-阿拉伯糖醇-d-半乳聚糖的糖蛋白,其特征是具有由α-阿拉伯糖,d和d组成的相似的单糖组成。 -半乳糖,1-岩藻糖,4-O-甲基-d-葡萄糖醛酸和d-葡萄糖醛酸残基。通过羧基还原,甲基化,高碘酸盐氧化,部分酸水解以及用糖苷和糖苷内切酶消化研究了碳水化合物成分的化学结构特征,这表明了(1→3)连接的β-d的主链。 -半乳糖基残基,其侧链由α-(1→6)-连接的d-半乳糖基残基组成。α-1-阿拉伯呋喃糖基残基作为单个非还原基团和作为O-2-或O-3-连接的残基连接至侧链的β-d-半乳糖基残基的O-3。单个α-1-呋喃核糖基端基与1-阿拉伯呋喃糖基残基的O-2相连,而4-O-甲基-β-d-吡喃葡糖基糖醛酸端基与d-半乳糖基残基相连。已显示O-α-1-呋喃核糖基-(1→2)-α-1-呋喃糖基端基负责1-阿拉伯-d-半乳
