ACAT (Acyl-CoA:cholesterol acyltransferase)

ACAT, or Acyl-CoA:cholesterol acyltransferase, is an important enzyme in the body that helps regulate cholesterol levels. It facilitates the conversion of free cholesterol into cholesteryl esters, which are stored in cells or transported in the bloodstream. This process is crucial for maintaining lipid balance and ensuring that excess cholesterol is safely stored rather than accumulating where it could cause problems, like in blood vessels. By managing cholesterol in this way, ACAT plays a key role in heart health and overall metabolic function.
