Which of the following lipoproteins is responsible for carrying
cholesterol from peripheral tissues (i.e skeletal muscle) back to the
liver? ANSWER: HDL
⫸ What is the primary role of LCAT (Lecithin-cholesterol
acyltransferase)? ANSWER: To esterify cholesterol transported by
HDL

and can potentially be used as fuel by all of the following tissues
except: ANSWER: liver
