alcohol dehydrogenase. Since the alcohol is oxidized, something has to be reduced. The substance that gets reduced is the oxidized form of nicotinamide adenine dinucleotide (abbreviated NAD+). The proposed mechanism for this redox reaction is given below. For the reduction half reaction NAD+ NADH. Based on the mechanism given above, indicate whether or not the given deuterated alcohol will produce NADD upon oxidation (NADD is the deuterated analog of NADH). (a) CH 3 CH 2 OD will produce NADD will not produce NADD (b) CD 3 CH 2 OH will not produce NADD will not produce NADD (c) CH 3 CD 2 OH will produce NADD will produce NADD Draw the indicated species given below. Use the X window to type in the R . (d) Oxidized species produced in the reaction given above. CC=O (e) Reduced species produced in the reaction given above. NC(=O)C1=CN([R])C=CC1 Solution or Explanation See section 15.11.
