The O-linked oligosaccharides of the jelly coat surrounding the eggs of Rana utricularia were analysed by 1H-NMR spectroscopy. Comparison of their structures with those characterized from seven other amphibians confirms that the carbohydrate chains of the jelly coat mucins are markers of the species. The new sequence GlcNAc(beta1-3)GlcNAc(beta1-6)[Gal(beta1-3)]GalNAc-ol is characteristic of Rana utricularia. The presence of blood group A determinants constitutes the main feature of this mucin.
用1H-核磁共振光谱法分析了牛蛙卵周围卵膜的O-连接寡糖。将其结构与其他七种两栖动物的特征结构进行比较,证实卵膜粘蛋白的碳水化合物链是物种的标志物。新序列GlcNAc(β1-3)GlcNAc(β1-6)[Gal(β1-3)]GalNAc-ol是牛蛙的特征序列。A血型决定簇的存在是这种粘蛋白的主要特征。
