And so what that means is these very long chain fatty acids will not be broken down, and they will increase in concentration in those individuals. In addition, paroxysomes have other functions. For instance, paroxysomes also synthesize those lipid molecules that are found in the myelin sheath around neurons, around the axons of neurons. And so if paroxysomes do not actually form correctly, what that means is we cannot form the myelin sheath. And so individuals with these conditions will basically have problems with their muscle tissue, with their liver, with their kidneys, as well as with the nervous system and other tissues. So, to summarize, we see that our fatty acid oxidation doesn't only take place in the matrix of the mitochondria, it also takes place in the paroxysome.
