6-Ketocholestanol is a compound produced by the oxidation of the 6-hydroxyl group of cholesterol. This derivative of cholesterol is believed to function as an antioxidant by neutralizing reactive oxygen species. Additionally, it has been demonstrated to impede the function of enzymes that are responsible for generating reactive oxygen species.
