<prompt> Which of the following enzymes is involved in process of both cholesterol and ketone bodies synthesis isHMG CoA reductaseHMG CoA synthaseHMG CoA lyaseThiolase  <response>: This enzyme is involved in both cholesterol synthesis as well as in ketone body synthesis.HMG CoA reductase is the rate limiting enzyme of the cholesterol synthesisHMG CoA lyase is the enzyme involved in ketone body synthesis .Thiolases also known as acetyl-Coenzyme A acetyltransferases ACAT are enzymes which converts two units of acetyl-CoA to acetoacetyl CoA in the mevalonate pathway.Thiolases are ubiquitous enzymes that have key roles in many vital biochemical pathways, including the beta oxidation pathway of fatty acid degradation and various biosynthetic pathways
