The Uses of Cholesteryl palmitate
Cholesteryl palmitate was used as standard in HPLC analysis of lipids from cooked ground beef and rat liver and mouse muscle tissue samples.
Definition
ChEBI: Cholesteryl palmitate is a cholesterol ester obtained by the formal condensation of cholesterol with palmitic acid. It has a role as a human metabolite and a mouse metabolite. It derives from a hexadecanoic acid.
Definition
A salt or ester of hexadecanoic acid.
Biological Activity
Cholesteryl palmitate is a cholesterol ester. It is a major cholesterol ester found in human meibum and has been 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.
