So we take the glucose one phosphate shown here and then we basically reacted with a urine triphosphate in the presence of the enzyme known as UDP glucose pyrophosphorylase. And what this enzyme basically does is it attaches the phosphoryl group and the urine onto this region. So we generate the following molecules. So this entire purple region came from the urine triphosphate and the pyrophosphate, the remaining Pyrophosphate was essentially kicked off. So this is the Pyrophosphate that was kicked off from the urine triphosphate. And the remaining portion of that urine triphosphate basically was attached onto this molecule to form the uriidine diphosphate UDP glucose.
