A PREVIOUS report¹ dealt with the enzymatic conversion of galactose-1-phosphate into glucose-1-phosphate and mentioned that a thermostable factor is necessary for the reaction. This factor has now been obtained practically pure, and for reasons given below will be referred to as uridine diphosphate glucose.
