So this is basically a two step process in which the cells basically activate the fatty acid molecule and prepared for transfer into the matrix of the mitochondria. Now, once we form that acyl coenzyme A, the next step is to basically transfer or the next step is to transport it into the matrix of the mitochondria. Now, before the acyl coenzyme A molecule can actually be transferred, it has to be converted into another molecule. And an important molecule that is used in this step is carnitine. So carnitine is essentially made from two different amino acids, and it's an alcohol molecule. More specifically, it's a zvitorion alcohol molecule.
