The activity of this plasma enzyme is responsible virtually for all plasma cholesterol esters in humans_______________?
Correct answer: C. Lecithin cholesterol acyl transferase (LCAT)
- A. HMG CoA reductase
- B. Pyrophospho mevalonate decarboxylase
- C. Lecithin cholesterol acyl transferase (LCAT)
- D. Phospho mevalonate kinase
Explanation
LCAT esterifies free cholesterol in plasma by transferring a fatty acid from lecithin to cholesterol, producing cholesteryl ester. This reaction accounts for virtually all cholesteryl ester formation in human plasma.
