In addition to the already knownonosaccharides fucose, xylose, mannose, galactose, glucose, N-acetylgalactosamine and N-acetylglucosamine, the carbohydrate part of the haemocyanin from Helix pomatia (Roman snail) contains 3-O-methylgalactose, and that from Lymnaea stagnalis (a freshwater snail) 3-O-methylgalactose and 3-O-methylmannose. The 3-O-methyl sugars were identified by g.l.c.-mas spectrometry of the corresponding trimethylsilyl methyl glycosides and the alditol acetates, and by co-chromatography with the synthetic reference substances.
除了已经为人所知的单糖岩藻糖、木糖、甘露糖、半乳糖、葡萄糖、N-乙酰半乳糖胺和N-乙酰葡糖胺外,苹果螺(罗马蜗牛)血蓝蛋白的碳水化合物部分含有3-O-甲基半乳糖,而椎实螺(一种淡水蜗牛)血蓝蛋白的碳水化合物部分含有3-O-甲基半乳糖和3-O-甲基甘露糖。通过对相应的三甲基硅烷基甲基糖苷和糖醇乙酸酯进行气相色谱-质谱分析,并与合成参考物质进行共色谱分析,鉴定出了3-O-甲基糖。
