A natural product found in Dioscorea (wild yam) species, it is used as the starting point for the commercial synthesis of a number of steroids, including cortisone, pregnenolone and progesterone. It has a role as an apoptosis inducer, an antiviral agent, an antineoplastic agent and a metabolite. It is a 3beta-sterol, a spiroketal, a hexacyclic triterpenoid and a sapogenin. It derives from a hydride of a spirostan."}]
