*  Cholesterol Esterification | Sigma-Aldrich
Distinct enzymes catalyze the cholesterol to cholesteryl ester conversion depending on the location of the reaction. The conversion of cholesterol to cholesteryl ester is catalyzed predominantly by lecithin:cholesterol acyltransferase (LCAT) in the peripheral tissues (see Figure 1). In the lumen, dietary cholesterol absorbed by enterocytes is esterified by acyl-coenzyme A: cholesterol acyltransferase 2 (ACAT2), which is found in both the intestine and liver (see Figure 2). ACAT1 is found in all tissues. LCAT and ACAT also differ in the sources they use for the acyl chains. LCAT uses phosphatidylcholine while ACAT uses acyl-CoA. Inhibiting these enzymes is one way of lowering the circulating lipids in plasma.. ...
