Cyclic oligoglucosides containing 5 to ca. 10 glucose residues in which an enclosed tubular space allows reception of a guest molecule to form a clathrate. The synonymous term Schardinger dextrins is not recommended. (α-Cyclodextrin has 6 glucose residues; β-cyclodextrin has 7.) Semi-systematically α-cyclodextrin is called cyclomaltohexaose.
