CAS number:2438-80-4    molecular formula:C6H12O5

overview

compound introduction

六碳糖的一种。并可以看做是一种甲基戊糖。自然界存在的岩藻糖绝大多数为L-岩藻糖,D构型的岩藻糖仅作为稀有糖,发现于一些糖甘类化合物中。L-岩藻糖较大量地存在于海藻及树胶中,也发现于某些细菌的多糖中。岩藻糖作为糖蛋白中糖链的组成部分,广泛存在于各类细胞表面的质膜上。岩藻糖比一般六碳糖在第六碳原子上少一个羟基,所以岩藻糖比其他单糖亲水性弱,而疏水性强一些。在某些血型物质分子中的岩藻糖是一定的血型的标记。通常从海藻中提取岩藻糖,先用酸处理,中和后,以苯腙形式析出,除去苯肼,可得α-L-岩藻糖结晶。 Usually used in studies of fucoidan polysaccharide containing glycans;studied as a glycan modifying carbohydrate that generates antigenic sites recognized by IgE antibodies;used as a substrate to identify, differentiate and characterize enzymes such as the fucosidase(s), l-fucose isomerase(s) and L-fucose dehydrogenase(s).
