In addition, we kick off the coenzyme A as shown here. Now, this acetyl coenzyme A is not the same as this acetyl Co enzyme A. So like I said, we're basically putting this malnozyme A away for just a moment because we're going to use it in one of these later steps. Now, once we generate this intermediate, the next step is to actually move this acetyl group from this sulf Hydrol to this sulf Hydrol shown here. And so in step number two, all we're doing is we're transferring this acetyl group onto this cysteine which acts as a temporary holding group. So it holds this molecule in place because ultimately what we're going to do is we're going to combine them and elongate that fatty acid chain so we see that in the next step, the Cetal group is transferred onto the 16 residue as shown in this particular diagram.
