| biological activity | Cholestenone (4-Cholesten-3-one) is an intermediate oxidation product of cholesterol, which is mainly metabolized in the liver. Cholestenone has high fluidity in the membrane, which affects the turnover and efflux of cholesterol. Cholestenone may lead to long-term defects in cell function. |
