gamma-Cyclodextrin,Cyclomaltooctaose, Cyclooctaamylose

Gamma-cyclodextrin (γ-CD) is a cyclic α-1,4-glucan linked oligosaccharide that is widely used in the food and pharmaceutical industries. In drug delivery, γ-CD can be used as a complexing agent because it forms an inclusion complex with a drug molecule. The complex of cyclodextrin increases the aqueous solubility and dissolution rate of the drug, which is useful for the delivery of the medical agent to a biological system.

Gamma-Cyclodextrin, also known as cyclomaltooctaose or cyclooctaamylose, belongs to the class of organic compounds known as oligosaccharides. These are carbohydrates made up of 3 to 10 monosaccharide units linked to each other through glycosidic bonds. Gamma-Cyclodextrin is soluble (in water) and a very weakly acidic compound (based on its pKa). Within the cell, Gamma-cyclodextrin is primarily located in the cytoplasm. Gamma-Cyclodextrin has an odorless taste. Gamma-Cyclodextrin is a potentially toxic compound.

Gamma-Cyclodextrin is a cyclic oligosaccharide with 8 D-glucose residues which are α-1,4-linked. Gamma-cyclodextrin is used in the food industry to encapsulate flavours and fragrances (Kfoury, 2016). Gamma-cyclodextrin can improve bioavailability of compounds with low water solubility, such as Coenzyme Q10, which has been used in nutraceuticals (Yukiko, 2017).
