Lecithin:cholesterol acyltransferase (LCAT) is an enzyme which converts free cholesterol of lipoprotein into esterified cholesterol. LCAT plays an important role in lipid metabolism especially in the reverse cholesterol transport system. As LCAT protein is synthesized by the liver, patients with liver disease showed a decreased ratio of cholesteryl ester to total cholesterol. Familial LCAT Deficiency and Fish Eye Disease are disorders that lack LCAT activity congenitally.

UI	MeSH Term	Description	Entries
D007862	Phosphatidylcholine-Sterol O-Acyltransferase	An enzyme secreted from the liver into the plasma of many mammalian species. It catalyzes the esterification of the hydroxyl group of lipoprotein cholesterol by the transfer of a fatty acid from the C-2 position of lecithin. In familial lecithin:cholesterol acyltransferase deficiency disease, the absence of the enzyme results in an excess of unesterified cholesterol in plasma.

D007863	Lecithin Cholesterol Acyltransferase Deficiency	An autosomal recessive disorder of lipoprotein metabolism caused by mutation of LECITHIN CHOLESTEROL ACYLTRANSFERASE gene. It is characterized by low HDL-cholesterol levels, and the triad of CORNEAL OPACITIES; HEMOLYTIC ANEMIA; and PROTEINURIA with renal failure.

D004796	Clinical Enzyme Tests	Analyses for a specific enzyme activity, or of the level of a specific enzyme that is used to assess health and disease risk, for early detection of disease or disease prediction, diagnosis, and change in disease status.

D004951	Esterification	The process of converting an acid into an alkyl or aryl derivative. Most frequently the process consists of the reaction of an acid with an alcohol in the presence of a trace of mineral acid as catalyst or the reaction of an acyl chloride with an alcohol. Esterification can also be accomplished by enzymatic processes.	Esterifications
