Gamma-cyclodextrin powder Classification.

γ-cyclodextrin has a larger cavity than β-cyclodextrin, so the cavity can contain a wider range of guest molecules; it has better water solubility. At room temperature 25°C, the solubility of γ-cyclodextrin is 25.6g/100ml, while the solubility of α-cyclodextrin is 12.7g/100ml water and the solubility of β-cyclodextrin is only 1.88g/100ml water. Its application prospects are broader than β-cyclodextrin, but due to its small production scale, its price is high, which limits the promotion of its application.

Uses of Gamma-cyclodextrin.

Uses of cyclodextrin in the field of chemistry Cyclodextrin is a valuable chemical reagent.

When it is present, the fluorescence intensity of the fluorescent pigment will increase significantly, so it can be used for the analysis of proteins and amino acids; it can also be used to separate long-chain organic compounds, racemates, etc. In addition, adsorbents made from cyclodextrin can be used as adsorption for chromatographic analysis. It can also be used as a complexing agent, and can also be used in enzyme activity research and tissue culture agents. This product should be sealed and stored in a dry place.

Resolve resolution of Gamma-cyclodextrin.

Product Methods of Bulk Gamma-cyclodextrin powder.

The hydrolyzed starch is acted on by cyclic maltodextrin glucose transferase (CGTase, EC2.4.1.19), and then purified by one of the following methods: l-cyclodextrin is precipitated with a complex of a macrocyclic compound, then extracted with n-decane, and the solvent is stripped; crystals are obtained from the purified mother liquor containing l-cyclodextrin by ion exchange or gel filtration chromatography; obtained by ultrafiltration and reverse osmosis membrane separation.
