Description
Cyclodextins (CD) are cyclic oligosaccharides composed of D-glucose units connected via α(1→4) glycosidic bonds. Common cyclodextins contain six (α-CD); seven (β-CD) or eight (gamma-CD) D-glucose units. Cyclodextins are sometimes derivitized through esterification at positions two, three and/or six. Gamma-cyclodextrin polymer is a chain of gamma-CD units potentially useful in the development of nanoassemblies/nanostructures and the delivery of drugs and molecules such as small-interfering RNA
