Stigmasterol with CAS 83-48-7
What is Stigmasterol?
Stigmasterol (chemical name: stigmasta-5,22-dien-3β-ol) is a plant sterol whose ring structure closely resembles cholesterol. It occurs naturally in soybean oil, rapeseed oil, Calabar bean and a range of legumes and vegetables, where it helps maintain the structure and fluidity of plant cell membranes.
Industrially, stigmasterol is extracted and purified from vegetable oil deposits and sterol residues into a white, water-insoluble crystalline powder. Its steroid backbone makes it a valuable starting material for the semi-synthesis of progesterone and other steroid hormone intermediates, in addition to its direct use in nutraceutical, cosmetic and food formulations.
