General description

γ-cyclodextrin (γ-CD) is a water-soluble cyclic octamer of D-glucose units linked via α(1→4) glycosidic bonds. Its ability to form several inclusion complexes with organic as well as inorganic compounds makes it a potential candidate in solid and solution state determinations.[1][2][3]

Application

γ-Cyclodextrin hydrate may be used to form inclusion complexes with steviol glycosides,[4] 1-propanol,[5] tempone and di-tert-butyl nitroxide[6] followed by their characterization by various analytical techniques.
Modifier used in experiments evaluating viability, integrity, and inflammation in genital epithelia upon exposure to pharmaceutical excipients and microbicides

Reactant used to investigate host-guest interactions between α−, β−and γ-cyclodextrins and vanadocene dichloride

We study by molecular dynamics simulations the hydration of beta-cyclodextrin. Our simulations show that within these barrel-shaped molecules hydrophobicity dominates, while at the top and bottom sides of the barrel interactions with water are mostly hydrophilic in nature. These results
