So notice this molecule is color coded. So the purple region is what eventually becomes this product here, the glyceroaldehyde three phosphate. But the blue section here is what eventually becomes the other different three carbon molecule known as dihydroxy acetone phosphate or simply DHAP. So an enzyme called aldelase catalyzes the breakdown of fructose one six bisphosphate that is produced in stage one into two different three carbon molecules, glycero, aldehyde, three phosphate and dihydroxy acetone phosphate, DHAP. Now, let's go back to a moment to stage one. So in stage one, the second step of stage one was to transform the glucose into the fructose isomer.
