The following figure shows the intermediate of the transketolase mechanism. Use arrow pushing to form the resonance stabilized enzyme intermediate. Show the mechanism for reaction of this intermediate with the given aldose, using the protonated acid/base residue suppliec by the enzyme. Clearly show the product of the reaction and make sure that the acid/base residue ends up in the protonated state at the end or your mechanism. H. CH,OH ce H-B H- OH OH OH CH,OPO,
