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. And this is an important step. And essentially, this is what we call a cycle because we begin with methionine, we move along and we generate that methionine back in the process. We also generate that sand molecule that can be used to methylate some particular target molecule.
