Characteristics & Applications:
γ-Cyclodextrin (gamma-CD) is a cyclic α-(1,4)-linked oligosaccharide consisting of eight glucose molecules. Like other Cyclodextrins, γ-Cyclodextrin can form inclusion complexes with a variety of organic molecules because the inner side of the torus-like molecule is less polar than the outer side. The cavity of γ-Cyclodextrin is bigger than that of β-Cyclodextrin, therefore it is used to inclusion with bigger drug moleculars. γ-Cyclodextrin is also a dietary fiber that can be used as a food additive.
