Description and Uses

24α-ethyl Cholesterol is a naturally occurring plant sterol with antioxidant, anticancer, anti-inflammatory, angiogenic, chemopreventive, and immunomodulatory activities. It inhibits the absorption of dietary and endogenously-produced cholesterol from the small intestine, reducing blood cholesterol concentrations. Because of its nutraceutical benefits, 24α-ethyl cholesterol has been used as a food additive intended to lower LDL cholesterol. 24α-ethyl Cholesterol (0.1 - 100 μM) can dose-dependently induce adipogenesis and lipolysis in rat primary preadipocytes as well as stimulate glucose uptake in differentiated adipocytes.

A common sterol in plants. Isolated from wheat germ oil, corn oil. Antilipemic. Used in the treatment of prostatic adenoma.This compound is a contaminant of emerging concern (CECs)
