So this is a two step process by which first we take the amino acid. We undergo a transamination step in which we basically transfer this green group onto a different molecule. We form glutamate. And the second step, we actually have that diamondation step. So we deaminate, we remove the alpha amino group, and we form the ammonium, at which point this ammonium can now be fed into the urea cycle. Now, let's begin by focusing on just this reaction here.
