    Product Description

    Cholesteryl stearate is a cholesterol ester.1 It has been used as an internal standard for the quantification of sterol esters in various plant tissues by quadropole time-of-flight (Q-TOF) MS. Cholesteryl stearate levels are decreased in coronary arteries with atherosclerotic plaques, isolated fatty streaks, and isolated atherosclerotic plaques compared with non-atherosclerotic coronary arteries.2

    WARNING This product is not for human or veterinary use.
