<prompt> Full form of LCAT is ?Lecithin cholesterol acyl transferaseLecithin cholesterol alkyltransferaseLecithin choline acetyltransferaseLecithin choline alcohol transferase  <response>: Ans. is a i.e., Lecithin cholesterol acyl transferase Lecithin-cholesterol acyl transferase LCAT is present in HDL and esterifies the cholesterol in HDL. Major activator of LCAT is Apo-Al. Apo-C1 can also activate LCAT.HDL-Cholesterol appears to be the best independent predictor of coronary aery disease inverse relationship than any other known risk factor. That means low HDL is a much stronger predictor of coronary aery disease than increased LDL cholesterol or increased total cholesterolThe intracellular cholesterol activates the intracellular enzyme acyl-CoA cholesterol acyl transferase ACAT. This enzyme catalyzes transfer of an acyl group from a fatty acid derivative to cholesterol, resulting in the formation of esterified choleserol, and this cholesterol ester is stored for subsequent use.
