So notice both of these are pento sugars, five carbon sugars. And when we transfer this section onto this molecule, we basically form, we extend that sugar by two carbons and we form a seven carbon sugar known as CETO heptolose seven phosphates. Now, if we take away these two carbons from the cellulose, we essentially form a trios, a three carbon sugar. And that three carbon sugar is known as glycero aldehyde three phosphate. So the products of step two, reaction two of this particular oxidative phase, is the CETO heptulose seven phosphate and the glyceroaldehyde three phosphate and is catalyzed by the transketilase. Now in process three of the non oxidative phase, we now take these two products and these two products will act as reactants in process three.
