So we see that the majority of amino acids inside our cells, more specifically our liver cells, hepatics basically undergo this two step process to deaminate that amino acid. Now, other amino acids such as Serene and three anine undergo other processes, processes to basically deaminate it. So in this case, we have a two step process that deaminates the amino acid. But for Serene and three anine, this is a single step process and it's catalyzed by single enzyme, a dehydrates. So we call it a dehydrates because there is a dehydration reaction that precedes a deamination reaction, as we'll see in just a moment. So for serine, we have serine dehydrates that basically deaminates the serine into Pyruvate and that forms Ammonium.
