Cholesteryl palmitate is a cholesterol ester used to form a stable tear film to study amphiphilic block copolymers as surfactants for dry eyes. Cholesteryl palmitate levels in amniotic fluid are decreased in pregnancies in which infants later developed respiratory distress syndrome and in patients with well-controlled diabetes. Levels of cholesteryl palmitate are increased in bronchoalveolar lavage fluid (BALF) from patients with chronic interstitial pneumonia.
