Common Name | Cholesteryl acetate |

Description | Cholesteryl acetate is a normal human cholesteryl ester present in diverse fluids and organs. Cholesteryl acetate is also present in foods. Food oxidation affects the quality and safety of the human diet by generating compounds with biological activities that can adversely affect health. In particular the susceptibility of cholesterol to oxidation is well known; certain products of cholesterol oxidation have been reported to produce cytotoxic, angiotoxic and carcinogenic effects. Cholesteryl ester (CE) is the major transport and storage form of cholesterol in lipoprotein particles and most cell types. Molecular composition of CE species is of high interest for arteriosclerosis research, i.e., as components of lipoprotein subclasses or in studies investigating the mechanisms involved in the generation of lipid laden foam cells. Thus, it has been shown that CE species in circulating plasma are strongly correlated with development of coronary heart disease. This may be related to specific CE species profiles generated by enzymes involved in lipoprotein metabolism like lecithin:cholesterol acyltransferase (EC 2.3.1.43, LCAT), acyl-coenzyme A:cholesterol acyltransferase 2 (EC 2.3.1.26, ACAT2) or cholesteryl ester transfer protein (CETP). The cholesteryl ester transfer protein has a key role in the metabolism of high-density lipoprotein (HDL), mediating the exchange of lipids between lipoproteins, resulting in the net transfer of cholesteryl ester from HDL to other lipoproteins and in the subsequent uptake of cholesterol by hepatocytes. By increasing the cholesteryl ester content of low-density and very-low-density lipoproteins, CETP promotes the atherogenicity of these lipoproteins. In addition, high plasma concentrations of CETP are associated with reduced concentrations of HDL cholesterol. (PMID: 10918380 , 16458590 , 9420339 , 3343104 , 6721900 , 7278520 ). |
