  • Detail

Feature:

Gamma-cyclodextrin is a ring-shapedmolecule made up of eight glucose units linked by alpha-1,4-bonds. Thesolubility 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.

Application:

Gamma-cyclodextrin can be used as a carrier for flavours, sweeteners, and colours. In chemistry it is a valuable chemical reagent. When gamma-cyclodextrin exists, fluorescence intensity of fluorescence pigment will become much bigger, so it is used as the analysis of protein and amino acid. Gamma-cyclodextrin is also used to separate long-chain organic compound, racemic modification and so on. Besides, the adsorbent made by gamma-cyclodextrin is used chromatographic analysis. It also can be used as complexing agent and cultivation agent instudy of enzymatic activity.
