摘要

Amylose, a linear polysaccharide with helical structure linked through α(1→4) glycosidic linkages, is a well-known host compound that forms inclusion complexes with relatively lower molecular weight compounds by noncovalent interaction between guest molecules and the cavity of amylose. However, little has been reported regarding the formation of inclusion complexes between amylose and polymeric compounds. The main difficulty in incorporating polymeric compounds into the amylose cavity is that the driving force for the binding is only caused by hydrophobic interactions. Amylose, therefore, does not have sufficient ability to include the long chains of polymers into its cavity.
