Question

the lipoproteins which mediate cholesterol clearance from the atheromatous plaque and are antiatherogenic are: high - density lipoprotein (hdl) intermediate - density lipoprotein (idl) very low - density lipoprotein (vldl) low - density lipoprotein (ldl)

Explanation:

HDL (high - density lipoprotein) is known as the "good cholesterol" as it helps in reverse cholesterol transport. It takes cholesterol from peripheral tissues (including atheromatous plaques) and transports it back to the liver for excretion. This process reduces the amount of cholesterol in the plaques and is anti - atherogenic. IDL (intermediate - density lipoprotein) is an intermediate in the metabolism of VLDL to LDL. VLDL (very low - density lipoprotein) is involved in the transport of triglycerides from the liver to peripheral tissues. LDL (low - density lipoprotein) is often called the "bad cholesterol" as it can deposit cholesterol in the arterial walls, promoting atherogenesis.

Answer:

High - density lipoprotein (HDL)
