Now, this molecule can basically be used for energy purposes, as we'll see in a future lecture. But this molecule must further undergo a process, the diamondation step, to basically generate that free ammonium. So let's look at two examples of these processes. So we have different aminotransferases, and two common examples are alanine and aspartate aminotransferases. So, as you might imagine, in this particular case, the beginning amino acid is alanine. In this case, it's aspartate.
