So this diamondation step is similar to this one here because we also use water in this hydrolysis step. So we essentially allow this group here to be kicked off. We form that Ammonium, and that Ammonium then goes into the urea cycle. So this is basically the process by which we deaminate amino acids. And by deaminating the amino acids, we basically form carbon skeletons and we form Ammonium. The Ammonium can be used in the urea cycle, and that carbon skeleton can be used to basically form energy molecules, as we'll see in a future lecture.
