环糊精(cyclodextrins,简写CD)又称环淀粉,是由6,7或8个D-葡萄糖以α-1,4-糖苷键联结而成的环状低聚糖,分别称为α-,β-或γ-环糊精,由于其存在一个疏水性的手性空腔,因此可与许多客体分子形成包络化合物(Inclusion complexes),是一类研究较多的天然模拟酶。通过化学键联将β-CD固载到高分子载体上,制得的β-CD高分子由于其载体机械性 Cyclodextrins (abbreviated CD), also known as amylose, are cyclic oligosaccharides linked by α, β-glucosidic linkages of 6, 7, or 8 D-glucose, which are called α- β-or γ-cyclodextrin, due to its presence of a hydrophobic chiral cavity, can form enveloping compounds with many guest molecules and is a well-studied class of natural mimic enzymes. The β-CD is immobilized on the polymer carrier by chemical linkage, and the obtained β-CD polymer has high mechanical strength
