OriginBeta sitosterol is a phytosterol compound synthesized from plant sterol starting materials or derived from vegetable oils through extraction. It is produced through chemical isolation and purification from plant sources like soybean and rapeseed oils.
Sitosterol is a member of the class of phytosterols that is stigmast-5-ene substituted by a beta-hydroxy group at position 3. It has a role as an antioxidant, an anticholesteremic drug, a sterol methyltransferase inhibitor, a mouse metabolite and a plant metabolite. It is a stigmastane sterol, a 3beta-hydroxy-Delta(5)-steroid, a C29-steroid, a member of phytosterols and a 3beta-sterol. It derives from a hydride of a stigmastane.
