And both ketone bodies and glucose molecules can be used by the cells of our body to generate high energy molecules. Now, in a person who has al captainuria, they basically have genes that are defective. So the genes that code for this enzyme humagentosate wants to dioxygenase, essentially code for a defective enzyme. And so this enzyme's activity isn't high or the enzyme doesn't have any activity at all. And so the homogeneous aid cannot be transformed into four male acetoacetate, and this will ultimately not be transformed into these two molecules. And so because of that, we're going to see that homogenesate will accumulate in our cells, in our tissues, in our blood.
