Feature
alpha-Cyclodextrin is a non-reducing cyclic saccharide comprised of six glucose units linked by alpha-1.4 bonds. It is produced by the action of cyclodextrin glucosyl transferase on hydrolysed starch syrups. The cavity of alpha-cyclodextrin is less than beta-cyclodextrin, so it is used to allow formation of inclusion complexes with little molecules. The solubility degree of Alpha-cyclodextrin in water is 14.5 g/100ml @ 25°C, so the situation that needs high solubility of cyclodextrin.
