3-hexanoyl-NBD-Cholesterol is a fluorescently-tagged cholesterol derivative with the hydrophilic NBD fluorophore attached to carbon 3, at the hydrophilic end of cholesterol, separated by a 6-carbon spacer. This design allows the cholesterol to properly orient in membrane bilayers while the fluorescent tag is presented outside of the bilayer. This should model the behavior of cholesterol in membranes better than the previously-used 25-NBD cholesterol, which positions NBD directly on the 25th carbon of cholesterol at the hydrophobic terminus. Fluorescently-tagged lipids have been used to study their interactions with proteins,1 their utilization by cells2 and liposomes,3 and for the development of assays for lipid metabolism.4,5
