摘要：

α-D-Ribofuranose 1-phosphate is several hundred times as reactive as α-D-glucopyranose 1-phosphate in both the acid-catalyzed hydrolysis and the hydrolysis of the undissociated phosphate. The activation energy for the acid hydrolysis is 6 kcal mol-1 lower for the ribose phosphate. Hydrolysis of the ribose phosphate monoanion makes no contribution to the over-all reaction. The catalytic efficiencies of the mineral acids for the hydrolysis of glucose 1-phosphate are HCl > HClO4 ~ H2SO4, and the positive salt effects of sodium chloride are considerably greater than those of sodium perchlorate. © 1969, American Chemical Society.
