d-Beta-Galaheptose and Some of its Derivatives' BY RAYMOND M. HANNAND C. S. HUDSON I n a recent publication2 experimental details of the preparation and properties of d-alpha-galaheptose and of some of its derivatives were recorded. Attention was called to the close similarity of the configuration of this newly crystallized sugar to that of Z-mannose, and the resulting similarity of the physical and chemical properties of these related sugars and of their compounds. In the present communication the properties of the epimeric d-beta-galaheptose, configurationally related to 1-glucose, and of some of its derivatives, will be described.
