UDP-(1)fructose was synthesized essentially by the method of Michelson or Roseman et al. The product obtained was much more stable to acid than UDP-fructose isolated from Jerusalem artichoke tubers by Umemura et al.7) and UDP-glucose. Hydrolysis time curves of UDP-(1)fructose and fructose-I-phosphate in 0.01N HCl and O.IN HCl both at 100°C are presented. It was concluded from these curves that UDP-(1)fructose was first hydrolyzed into UMP and fructose-I-phosphate, and then fructose-I-phosphate was hydrolyzed more slowly into free fructose and inorganic phosphate.
