Now, once the palmitolial coenzyme A is in the matrix of the mitochondria, it then undergoes three cycles of beta oxidation, the same beta oxidation pathway that we discussed in the previous lecture. So once this undergoes three cycles of beta oxidation, it produces two acetoco enzyme A molecules and it shortens this 16 carbon molecule into a ten carbon molecule. This CIS delta three in oil coenzyme A molecule. Now, the problem with this molecule is the following. The first enzyme that catalyzes step one of beta oxidation, the acyl coenzyme adhdrogenase, cannot actually act on this molecule. Why?
