What is "cycloamylose"

n. (context carbohydrate English) any of a class of cyclic oligomers of glucose; they have a toroidal shape and bind tightly with many aromatic compounds, the guest molecule fitting into the cavity like a key and lock; they mimic the action of several enzymes

Cycloamyloses are cyclic α-1,4 linked glucans comprising dozens or hundreds of glucose units. Chemically they are similar to the much smaller cyclodextrins, which are typically composed of 6, 7 or 8 glucose units.
