Approximately 200 enzymes require NAD or NADP+. We will go through some selected functions of NAD and NADP+. The following figures and legends show and describe the functions of NAD and NADP+.
HMG CoA reductase, the rate-limiting enzyme in cholesterol synthesis, uses NADPH. NADPH is also used by the antioxidant enzyme glutathione reductase as shown in the link below6.
