WebMar 16, 2024 · CYP11A1 mitochondrial enzyme commonly known as 20,22-desmolase or cholesterol side-chain cleavage enzyme (or P450ssc) which catalyzes the initial reaction of steroid hormone synthesis; converts cholesterol to pregnenolone; active enzyme is a complex CYP11A1, adrenodoxin reductase, and ferredoxin-1 (also known as adrenadoxin) WebAug 23, 2024 · Contrary to StAR, the gene expression of P450ssc was regulated by diets in males but not in females. This may be related to the fact that the gene expression of P450ssc (cyp11a1) correlates better with testosterone production (Reference Peñaranda, Morini and Tveiten 56).
