Popis

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.

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.

Other Notes

Cyclodextrins are low molecular weight organic molecules which form watersoluble complexes with various compounds (guests); Enzyme model
