Number one is the triglycerides must be broken down and mobilized into fatty acids within the fat cells of our body. And once these fatty acids are mobilized, they travel into the bloodstream and then move into the cytoplasm of the target cell. And once inside that target cell, the second thing that must happen is the fatty acid must be activated and it must be transported into the matrix of the mitochondria. Now, the third thing that must happen is once that fatty acid is inside the matrix of the mitochondria of that target cell, the fatty acid must be broken down into acetyl coenzyme A molecules. And this is what I'd like to focus on in this lecture. So I'd like to focus on the degradation, the breakdown of fatty acids into acetylcoenzone A molecules as it takes place in the matrix of the mitochondria of the target cell.
