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. Linoleate is an 18 carbon fatty acid that contains two double bonds. One double bond is between carbon nine and ten, and the other double bond is between carbon twelve and carbon 13. Now, in the same exact way that we discussed in this particular case, where we take the palmatoliate, we activate it in a cytoplasm and then move it into the mitochondria, the matrix of the mitochondria.
