Bio lactol

Lactol - Wikipedia. In organic chemistry, a lactol is the cyclic equivalent of a hemiacetal or a hemiketal bio lactol. The compound is formed by the intramolecular nucleophilic addition of a hydroxyl group to the carbonyl group of an aldehyde or a ketone. A lactol is often found as an equilibrium mixture with the corresponding hydroxyaldehyde. The equilibrium can favor either direction depending on rin…
