Cholesterol is a crucial component of biological membranes and can interact with other membrane components through hydrogen bonding. NMR spectroscopy has been used previously to investigate this bonding, however this study represents the first O-17 NMR spectroscopy study of isotopically enriched cholesterol. We demonstrate the O-17 chemical shift is dependent on hydrogen bonding, providing a novel method for the study of cholesterol in bilayers.
