This is known as UDP galactose. We also form glucose one phosphate because that uridine and a single phosphoryl group have been removed from the UDP glucose. And so we form the glucose one phosphate. So these are the two products of step two. Now, this product will go on to carry out step three, and this product will go on to carry out step four. Now, step three is important because in step three, what we want to do is we want to reform the UDP glucose.
