Well, in the next step, we basically want to remove that adenosine group. And so what happens is this entire group is actually removed, and the enzyme that catalyzes this is adenosyl homocysteinease. And so the product molecule that we form is the homocysteine. And notice we still have that blue section that ultimately came from here that will become part of the succinal coenzyme A. Now, let's stop here for just a moment. So before we take the homocysteine and continue on the pathway to actually generate the succinctoenzyme A, what also could actually happen and what we should talk about is the fact that homocysteine can be used to actually regenerate that methionine.
