直链淀粉复合物制备及表征的研究进展

Progress on Preparation and Characterization of Amylose Complexes

在配体存在的条件下,直链淀粉经历构象变化与配体发生疏水性作用或分子间内部的氢键作用,形成具有亲水性表面和疏水性内螺旋通道的左手单螺旋结构。因此,直链淀粉不仅可包封疏水性客体,而且可作为生物活性化合物的可能载体形成复合物。主要讨论直链淀粉-复合物不同制备方式及表征方法,尤其是直链淀粉-醇类复合物的制备及表征。

In the presence of ligand, amylose undergoes a conformation change of hydrophobic interaction and hydrogen bond interaction inside of intermolecular. The structure of complex is a single, left-handed helix with hydrophilic surface and hydrophobic inside helical channel. Hence, amylase not only can form complex with encapsulating hydrophobic object, but also can be as a possible vehicle for bioactive compounds. Primarily discuss the different preparation and characterization methods of amylose-complexes, especially the preparation and characterization of amylose-alcohol complexes.
