WebCyclic hemiacetals and hemiketals are sometimes called lactols. [3] They often form readily, especially when they are 5- and 6-membered rings. In this case an intramolecular OH group reacts with the carbonyl group. Glucose and many other aldoses exist as cyclic hemiacetals whereas fructose and similar ketoses exist as cyclic hemiketals.

WebSep 12, 2024 · In its cyclic form the anomeric (hemiacetal) carbon is involved in two carbon-carbon bonds. This means that when we open the molecule up to its open chain form the anomeric carbon becomes a keto carbonyl group. Fructose is thus an example of a ketose, a sugar in which the carbonyl group is a ketone rather than an aldehyde. Polysaccharides
