产品描述

General description

α-Cyclodextrin (α-CD) is a water-soluble cyclic oligosaccharide that consists of six glucopyranose units linked by α-(1,4) bonds. It is commonly used to form inclusion complexes (ICs) with a wide range of organic compounds.[5][6]

Application

α-Cyclodextrin may be used to synthesize a polymer inclusion complex (PIC) with poly(ethylene glycol) (PEG)-modified chitosans. These PICs can self-assemble to form supramolecular hydrogels.[7]

Other Notes

环糊精为低分子量有机分子,可与不同化合物(客体)形成水溶性配合物[1][2][3];酶模型[4]
