General description

β-Cyclodextrin is a cyclic oligosaccharide consisting of seven glucose subunits joined by α-(1,4) glycosidic bonds forming a truncated conical structure. It is widely used in food, pharmaceutical, cosmetics, and chemicals industries.

Application

β-Cyclodextrin is used as a complexing agent in drug delivery because it forms an inclusion complex with a drug molecule. The complex of cyclodextrin increases the aqueous solubility, dissolution rate and bioavailability of poorly water-soluble drugs, which is useful for the delivery of the medical agent to a biological system.

Cyclodextrins

Many metabolically important compounds, such as lipid-soluble vitamins and hormones, have very low solubilities in aqueous solutions. Various techniques have been used to solubilize these compounds in tissue culture, cell culture, or other water-based applications.
