This enzyme catalyzed the transformation into UDP galactose. So this becomes UDP galactose, and the UDP glucose becomes glucose one phosphate. And then the glucose one phosphate can basically go on to form glucose six phosphate, which can be fed, incorporated into the glycolytic pathway, and the UDP galactose can be transformed into the UDP glucose. That's what happens on the normal condition. So normally, the galactose is transformed into galactose one phosphate. Then this one is transformed into this molecule and a glucose one phosphate.
