So essentially attached onto carbon number one of glucose, we have the uradine diphosphate group. And what this transferase enzyme does is it transfers up a sporal group from the urine diphosphate glucose onto this phosphate region here. And so we go from galactose one phosphate to UDP galactose. So this molecule is known as uridine diphosphate galactose. And notice we transferred the phosphoryl group as well as that uridine. And so this is the molecule that is formed.
