Cholesterol Ester: Lysolecithin Acyltransferase Activity of the Aorta
Enzyme-catalyzed transfer from lecithin on cholesterol to form cholesterol ester and lysolecithin (LCAT+) 1/ in the arterial wall has been found (1) but not much is known about the reaction in reverse direction. It seemed to be of interest, therefore, to investigate the cholesterol ester: lysolecithin acy1 transfer activity (LCAT-) of the aortic wall, as compared with LCAT+ and cholesterol esterase activities.
