So enol coenzyme a hydrates, the second enzyme in the beta oxygen pathway, cannot actually act on this molecule. And so, once again, we have to use some type of enzyme to basically transform this molecule into a molecule that can ultimately be fed, can be incorporated into the beta oxidation pathway. And the enzyme that carries out this process is known as two four dienol coenzyme a reductase. It basically uses an NADP plus molecule to basically oxidize this intermediate into this molecule, at the same time reducing and forming the NADPH. Now, once we form this molecule, a trans delta three enoll coenzyme a. Now an isomerase, this isomerase here can act on this molecule, basically moves that double bond onto this location here.
