Key Concepts

Lobry de Bruyn-Alberda van Ekenstein Transformation

This is a specific base-catalyzed rearrangement mechanism in carbohydrate chemistry where an aldose converts into a ketose and an epimer via an enediol intermediate. It illustrates how sugars like glucose can interconvert into other isomeric forms under alkaline conditions, establishing an equilibrium mixture of different sugars.

Carbohydrate Isomerization

This refers to the process by which one carbohydrate (sugar) is converted into another isomer under specific reaction conditions, such as base catalysis. It involves changes in the arrangement of atoms within the molecule, leading to different stereochemical and functional properties while maintaining the same molecular formula.

Enediol Intermediate

An enediol is a reactive intermediate characterized by a carbon–carbon double bond with hydroxyl groups attached to both carbons. In the context of carbohydrate chemistry, its formation through deprotonation is a key mechanistic step that facilitates the isomerization process, allowing for the interconversion between aldoses and ketoses.
