(e) Pyruvic acid is converted to lactic acid via a Lactate dehydrogenase (LDH)-catalyzed reduction as shown below. Prior to reduction, pyruvic acid binds to the binding site of the LDH enzyme via intermolecular interactions shown below. Explain how hydrogen bonding to the keto oxygen facilitates a faster reaction.
