Aldoses isomerize to ketoses in the Lobry-de Bruyn-van Ekenstein transformation. Aldose differs from ketose in that it has a carbonyl group at the end of the carbon chain whereas the carbonyl group of ketose is in the middle. The Lobry-de Bruyn-van Ekenstein transformation also known as the Lobry-de Bruyn-van-Alberda-van-Ekenstein transformation is a base catalyzed Aldose-Ketose-Isomerization in carbohydrate chemistry [1] . A typical rearrangement reaction is that between glyceraldehyde and dihydroxyacetone in a chemical equilibrium. ...
