Description

CE(20:1(11Z)) is a cholesterol fatty acid ester or simply a cholesterol ester (CE). Cholesterol esters are cholesterol molecules with long-chain fatty acids linked to the hydroxyl group. They are much less polar than free cholesterol and appear to be the preferred form for transport in plasma and for storage. Cholesterol esters do not contribute to membranes but are packed into intracellular lipid particles or lipoprotein particles. Because of the mechanism of synthesis, plasma cholesterol esters tend to contain relatively high proportions of C18 fatty acids. Cholesterol esters are major constituents of the adrenal glands and they also accumulate in the fatty lesions of atherosclerotic plaques. Cholesterol esters are also major constituents of the lipoprotein particles carried in blood (HDL, LDL, VLDL). The cholesterol esters in high-density lipoproteins (HDL) are synthesized largely by transfer of fatty acids to cholesterol from position sn-2 (or C-2) of phosphatidylcholine catalyzed by the enzyme lecithin cholesterol acyl transferase (LCAT). The enzyme also promotes the transfer of cholesterol from cells to HDL. As cholesterol esters accumulate in the lipoprotein core, cholesterol is removed from its surface thus promoting the flow of cholesterol from cell membranes into HDL. This in turn leads to morphological changes in HDL, which grow and become spherical. Subsequently, cholesterol esters are transferred to the other lipoprotein fractions LDL and VLDL, a reaction catalyzed by cholesteryl ester transfer protein. Another enzyme, acyl-CoA:cholesterol acyltransferase (ACAT) synthesizes cholesterol esters from CoA esters of fatty acids and cholesterol. Cholesterol ester hydrolases liberate cholesterol and free fatty acids when required for membrane and lipoprotein formation, and they also provide cholesterol for hormone synthesis in adrenal cells. Cholesteryl eicosapentaenoic acid is a cholesteryl ester. A cholesteryl ester is an ester of cholesterol. Fatty acid esters of cholesterol constitute about two-thirds of the cholesterol in the plasma. Cholesterol is a sterol (a combination steroid and alcohol) and a lipid found in the cell membranes of all body tissues, and transported in the blood plasma of all animals. The accumulation of cholesterol esters in the arterial intima (the innermost layer of an artery, in direct contact with the flowing blood) is a characteristic feature of atherosclerosis. Atherosclerosis is a disease affecting arterial blood vessels. It is a chronic inflammatory response in the walls of arteries, in large part to the deposition of lipoproteins (plasma proteins that carry cholesterol and triglycerides). In patients with triglyceride levels above 500 mg/dl, approximately 4 g/day of eicosapentaenoic acid reduces triglyceride levels 45% and very low-density lipoprotein cholesterol levels by more than 50%. Physical exercise and fish oil (a rich source of eicosapentaenoic acid) suppress the activity of endothelial lipase (EL) and this, in turn, enhances the plasma concentrations of HDL cholesterol. EL has been shown to have a significant role in modulating the concentrations of plasma HDL. (PMID: 17461707 , 15664301 , 15524182 , 15485592 ).

Enzymes

Enzyme Details

1. Phosphatidylcholine-sterol acyltransferase

General function:: Involved in phosphatidylcholine-sterol O-acyltransferase activity
Specific function:: Central enzyme in the extracellular metabolism of plasma lipoproteins. Synthesized mainly in the liver and secreted into plasma where it converts cholesterol and phosphatidylcholines (lecithins) to cholesteryl esters and lysophosphatidylcholines on the surface of high and low density lipoproteins (HDLs and LDLs). The cholesterol ester is then transported back to the liver. Has a preference for plasma 16:0-18:2 or 18:O-18:2 phosphatidylcholines. Also produced in the brain by primary astrocytes, and esterifies free cholesterol on nascent APOE-containing lipoproteins secreted from glia and influences cerebral spinal fluid (CSF) APOE- and APOA1 levels. Together with APOE and the cholesterol transporter ABCA1, plays a key role in the maturation of glial-derived, nascent lipoproteins. Required for remodeling high-density lipoprotein particles into their spherical forms.
Gene Name:: LCAT
Uniprot ID:: P04180
Molecular weight:: 49577.545

Enzyme Details

2. Lysosomal acid lipase/cholesteryl ester hydrolase

General function:: Involved in lipid metabolic process
Specific function:: Crucial for the intracellular hydrolysis of cholesteryl esters and triglycerides that have been internalized via receptor-mediated endocytosis of lipoprotein particles. Important in mediating the effect of LDL (low density lipoprotein) uptake on suppression of hydroxymethylglutaryl-CoA reductase and activation of endogenous cellular cholesteryl ester formation.
Gene Name:: LIPA
Uniprot ID:: P38571
Molecular weight:: 45418.71

Enzyme Details

3. Bile salt-activated lipase

General function:: Lipid transport and metabolism
Specific function:: Catalyzes fat and vitamin absorption. Acts in concert with pancreatic lipase and colipase for the complete digestion of dietary triglycerides.
Gene Name:: CEL
Uniprot ID:: P19835
Molecular weight:: 79666.385

Enzyme Details

4. Liver carboxylesterase 1

General function:: Lipid transport and metabolism
Specific function:: Involved in the detoxification of xenobiotics and in the activation of ester and amide prodrugs. Hydrolyzes aromatic and aliphatic esters, but has no catalytic activity toward amides or a fatty acyl-CoA ester. Hydrolyzes the methyl ester group of cocaine to form benzoylecgonine. Catalyzes the transesterification of cocaine to form cocaethylene. Displays fatty acid ethyl ester synthase activity, catalyzing the ethyl esterification of oleic acid to ethyloleate.
Gene Name:: CES1
Uniprot ID:: P23141
Molecular weight:: 62520.62

Enzyme Details

5. Sterol O-acyltransferase 2

General function:: Involved in acyl-CoA binding
Specific function:: Plays a role in lipoprotein assembly and dietary cholesterol absorption. In addition to its acyltransferase activity, it may act as a ligase. May provide cholesteryl esters for lipoprotein secretion from hepatocytes and intestinal mucosa.
Gene Name:: SOAT2
Uniprot ID:: O75908
Molecular weight:: 59895.735

Enzyme Details

6. Sterol O-acyltransferase 1

General function:: Involved in acyl-CoA binding
Specific function:: Catalyzes the formation of fatty acid-cholesterol esters. Plays a role in lipoprotein assembly and dietary cholesterol absorption. In addition to its acyltransferase activity, it may act as a ligase.
Gene Name:: SOAT1
Uniprot ID:: P35610
Molecular weight:: 58130.665

Enzyme Details

7. Scavenger receptor class B member 1

General function:: Involved in cell adhesion
Specific function:: Receptor for different ligands such as phospholipids, cholesterol ester, lipoproteins, phosphatidylserine and apoptotic cells. Probable receptor for HDL, located in particular region of the plasma membrane, called caveolae. Facilitates the flux of free and esterified cholesterol between the cell surface and extracellular donors and acceptors, such as HDL and to a lesser extent, apoB-containing lipoproteins and modified lipoproteins. Probably involved in the phagocytosis of apoptotic cells, via its phosphatidylserine binding activity. Receptor for hepatitis C virus glycoprotein E2. Binding between SCARB1 and E2 was found to be independent of the genotype of the viral isolate. Plays an important role in the uptake of HDL cholesteryl ester
Gene Name:: SCARB1
Uniprot ID:: Q8WTV0
Molecular weight:: 60877.4

Enzyme Details

8. Neutral cholesterol ester hydrolase 1

General function:: Involved in hydrolase activity
Specific function:: Hydrolyzes 2-acetyl monoalkylglycerol ether, the penultimate precursor of the pathway for de novo synthesis of platelet-activating factor. May be responsible for cholesterol ester hydrolysis in macrophages, thereby contributing to the development of atherosclerosis. Also involved in organ detoxification by hydrolyzing exogenous organophosphorus compounds. May contribute to cancer pathogenesis by promoting tumor cell migration
Gene Name:: NCEH1
Uniprot ID:: Q6PIU2
Molecular weight:: 45807.4
