Now this is an important step because now the second enzyme, namely the enolco enzyme A hydratase e, and the beta oxidation pathway can now act on this molecule and then transform it into ultimately acetylco enzyme A. And then we can have three more cycles of beta oxidation to basically release and produce all those acetylco enzyme A molecules. So we see that anytime we ingest a fatty acid that contains an odd number of double bonds, this is basically what we're going to find taking place. So we're going to have this isomerase that will transform the CIS delta three null coenzyme A molecules into the trans delta two nullenzine coenzyme A molecule so that they can be fed into the beta oxidation pathway. Now, what about the case when we have an even number of double bonds in that fatty acid? So to demonstrate what our cells actually do, let's discuss linoleate.
