环糊精(CD)是由若干葡萄糖残基以α-(1,4)-糖苷键连接而成的大环化合物,它最大的特征是能在其分子空腔内结合多种有机、无机分子,因此 CD 及经化学修饰得到的一些衍生物可以较好地模拟天然酶的一些特性。对 CD 进行化学修饰的一个重要步骤往往是对它的羟基进行选择性的磺酰化。β-CD 是由7个葡萄糖残基组成的,其伯羟基的单对甲苯磺
Cyclodextrin (CD) is a kind of macrocyclic compound composed of several glucose residues linked by α- (1,4) -glycosidic bonds. Its biggest feature is that it can combine many kinds of organic and inorganic molecules in its molecular cavity , So some derivatives of CD and chemical modification can better simulate some characteristics of natural enzyme. An important step in the chemical modification of a CD is often the selective sulfonylation of its hydroxyl group. β-CD is composed of seven glucose residues, the primary hydroxyl group of toluene sulfonate
