WebGalactose, for example, is phosphorylated in a manner analogous to step [1] of glycolysis. The reaction, catalyzed by a galactokinase, results in the formation of galactose 1-phosphate. This product is transformed to glucose 1-phosphate by a sequence of reactions requiring as a coenzyme uridine triphosphate (UTP). WebIn this reaction, catalyzed by galactose-1-phosphate uridyltransferase, galactose replaces glucose binding to UDP. 3. UDP-glucose formation. UDP-galactose is converted into UDP-glucose by an epimerase (UDP-galactose 4-epimerase), NAD-linked.
