The first step in the biochemical breakdown of progesterone is a reaction involving 20a-hydroxysteroid dehydrogenase (20a-HSDH), an enzyme which catalyzes the reduction of a ketone group at position 20 of steroids. a. Draw the product that forms when progesterone is reduced by the action of 20a-HSDH and NADH. b. Draw the product that forms when 1 mol progesterone is reacted with 3 mol of H2 in the presence of Pt.
