Cholesterol esterase is a hydrolase that catalyzes the conversion of ingested cholesterol ester to free cholesterol and free fatty acid [1]. Cholesterol esterase exhibits proatherogenic properties by facilitating the conversion of the larger and less atherogenic lipoprotein particles to smaller and more atherogenic lipoprotein subspecies [2]. Cholesterol esterase can be covalently immobilized on the polyaniline film to develop a biosensor for cholesterol measurement[3].
In vitro, Cholesterol esterase (100mU/ml) treatment for 3 hours promotes the proliferation and migration of human umbilical vein endothelial cells (HUVECs) [4].
