QUESTION
Which one of the following lipoproteins is responsible for picking-up excess cholesterol in peripheral tissue capillary bed?
OPTIONS
(A) Chylomicrons
(B) YLDL
(C) LDL
(D) HDL
ANSWER
(D) HDL
EXPLANATION
HDL is the correct option because high-density lipoprotein participates in reverse cholesterol transport by collecting excess cholesterol from peripheral tissues and transporting it toward the liver for processing and excretion. Chylomicrons mainly transport dietary lipids, VLDL transports endogenous triglycerides, and LDL primarily delivers cholesterol from the liver to peripheral tissues.
