Small group big role

Cyclodextrin is a cyclic oligosaccharide from Bacillus species produce some glycosyltransferase and generated from starch, characteristics of cyclodextrin is most marked with a three-dimensional chiral cavity ring outer ring of hydrophobic hydrophilic, and there is a certain size, this kind of special structure, which has many special the physicochemical properties of the ring structure and the cavity can envelop different compounds, such as organic molecules, rare gases and inorganic compounds, the formation of inclusion complexes by envelope compounds known as known as the main object, cyclodextrin. The guest molecules are bound by cyclodextrins by Fan Dehua gravity and hydrogen bonds, resulting in a new inclusion phase. At present, cyclodextrins and their derivatives have become the most important subject in supramolecular chemistry, and have been widely used in medicine, food, chemical, materials, environmental protection and analytical chemistry. The industry is mainly reflected in the application of cyclodextrin can be entrapped many organic and inorganic compounds, as quality improver, stabilizer, drug carrier and adsorbent in the field of food, medicine, chemical industry, environmental protection and other important purposes.
