The resulting molecule has a hemiacetal or hemiketal group, depending on whether the linear form was an aldose or a ketose. The reaction is easily reversed, yielding the original open-chain form. In these cyclic forms, the ring usually has five or six atoms.
WebFive and six-membered rings are favored over other ring sizes because of their low angle and eclipsing strain.
