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. So we see that Pyruvate enters gluconeogenesis as Pyruvate, lactate enters gluconeogenesis as Pyruvate, and glycerol enters gluconeogenesis as DHAP. Dihydroxy acetone phosphate. Now, what about the final type of precursor molecule?
