物化性质 | 环糊精是呈环状的低聚葡萄糖。通常是由6个、7个或8个葡萄糖单元通过α,1-→4键环状相至连接的结晶体。分别称α-、β或γ-环糊精[α-Cyclodex-trinak Cyclohexaamylose,β-Cyclodextrin或Cyclo-heptaamylose,γ-Cyclodextrin或Cyclooctaamylose]。环糊精不具有还原性末端,对酸有一定的稳定性,普通的淀粉酸难于将它们水解。各种环糊精的性质见下表: α- 葡萄糖数目 6 分子量 972.86空间直径(×10-8m) 6 空穴深度(×10-8m) 7-8 结晶形状(无水) 针状 比旋光度[α]D25水 +150.5° 溶解度 14.5(g/100g水,25℃)与碘的颜色反应 青 |
