Reactions
NAD+ + Dehydroepiandrosterone = NADH + H+ + Androstenedione
NAD+ + Pregnenolone = NADH + H+ + Progesterone
NADH + H+ + Testosterone = NAD+ + Androstenediol
3-Oxo-delta5-steroid = 3-Oxo-delta4-steroid
NADH + H+ + Cortisol = NAD+ + 11beta,17alpha,21-Trihydroxypregnenolone
NAD+ + 17alpha-Hydroxypregnenolone = NADH + H+ + 17alpha-Hydroxyprogesterone
NAD+ + 21-Hydroxypregnenolone = NADH + H+ + 11-Deoxycorticosterone
NADH + H+ + 16alpha-Hydroxyandrost-4-ene-3,17-dione = NAD+ + 16alpha-Hydroxydehydroepiandrosterone
NADH + H+ + 11-Deoxycortisol = NAD+ + 17alpha,21-Dihydroxypregnenolone
