Abstract: In acidified water solutions of molybdate, aldoses epimerize under the formation of equilibrium mixtures in which the epimer having trans relationship of the hydroxyl groups at C-2 and C-3 predominates. The epimerization of both D-glucose and D-mannose gives the equilibrium mixture of D-glucose and D-mannose in the ratio 75 25. A tentative mechanism for this reaction is suggested and the preparation of D-mannose from D-glucose is described.
