And once inside these hepatitis, they undergo a two step process. The first step is catalyzed by glycerol kinase, and we use an ATP molecule. And so we transform glycerol into glycerol phosphate. And in the second step, that is catalyzed by glycerol phosphate dehydrogenase, we basically use an NAD plus molecule to oxidize the glycerol phosphate into DHAP. So dihydroxy acetone phosphate. And it's this molecule that enters the process of gluconeogenesis and begins the conversion of this molecule into glucose.
