Now, another thing that I'd like to mention is the following. If the liver cell produces these ketone bodies, what stops the liver cells from actually generating back these acetyl acetal coenzyme a molecules? Well, inside the liver cells, it actually does not contain co enzyme a transphrase. So even though the other cells of our body do have coenzyme a transferase inside the mitochondrial matrix, the liver cells do not. And that's important because we don't want the liver to actually eat these ketone bodies to digest these ketone bodies. So the liver generates the ketone bodies, but it cannot use the ketone bodies, so it can actually move those ketone bodies into the bloodstream so that other cells can use them.
