                        Cyclodextrin is a general term for a series of cyclic oligosaccharides produced by amylose under the action of cyclodextrin glucosyltransferase produced by Bacillus, usually containing 6 to 12 D-glucopyranose units. Among them, the molecules with 6, 7 and 8 glucose units, which have been studied more and have important practical significance, are called alpha-, beta- and gama-cyclodextrins respectively (Fig. 1). According to X-ray crystallography, From the results of infrared spectroscopy and nuclear magnetic resonance spectroscopy, it was determined that each D(+)-glucopyranose constituting the cyclodextrin molecule was in a chair conformation. Each glucose unit was linked by 1,4-glycosidic bond to form a ring. Due to the connection The glycosidic bond of the glucose unit cannot rotate freely, and the cyclodextrin is not a cylindrical molecule but a slightly conical ring. is a general term for a series of cyclic oligosaccharides produced by amylose under the action of cyclodextrin glucosyltransferase produced by Bacillus, usually containing 6 to 12 D-glucopyranose units.
