Cholesteryl palmitate, a cholesterol ester, is a significant component of human meibum. It has been utilized to create a stable tear film for the investigation of surfactants called amphiphilic block copolymers. Cholesteryl palmitate is formed by the formal condensation of cholesterol with palmitic acid. Also known as CE or cholesterol palmitate, 16:0 cholesteryl ester belongs to a class of organic compounds called cholesteryl esters, which contain an esterified cholestane moiety. Cholesteryl palmitate is utilized in research to study lipid behavior and membrane composition. Its structure, combining cholesterol with palmitic acid, makes it representative of naturally occurring cholesterol esters, facilitating studies on lipid metabolism, membrane fluidity, and the role of lipids in cell signaling. This compound aids in understanding the physicochemical properties of lipids in biological membranes and their implications for cell function and health.
