4. Feature of Gamma-cyclodextrin

Gamma-cyclodextrin has a larger cavity than b- cyclodextrin, so the cavity can be covered with a wider range of guest molecules; gamma cyclodextrin has a better solubility in water.

Gamma-Cyclodextrin is a ring-shaped molecule made up of eight glucose units linked by alpha-1,4-bonds. The solubility degree of gamma-cyclodextrin in water is 23.2 g/100ml @ 25°C, which is higher than alpha-cyclodextrin and beta-cyclodextrin, and it is used to allow formation of inclusion complexes with bigger molecules.
