So in this step, we basically have the dehydration step in which this group and this group are combined to form water. They are removed, and we form this double bond. So the three hydroxy acid ACP dehydrates domain of FAS catalyzes the dehydration reaction in which we generate a double bond and release water, thereby forming a molecule that we call Croatinil that is attached onto the ACP. So we have a condensation step, we have a reduction step, we have a dehydration step. And in step seven, this is a second reduction step. And again, we use NADPH as our reducing molecule.
