And once the ACL coenzyme a dehydrogenase acts acts on this molecule, it forms a double bond between carbon two and carbon three. And so he formed this molecule, which we call the 24 dienol coenzyme a intermediate. Now, the problem with this molecule is this molecule is not a substrate molecule to enol coenzyme a hydrate. 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.
