HDL cholesterol, or high-density lipoprotein cholesterol, earns its "good" cholesterol moniker by virtue of its protective role in cardiovascular health.
HDL particles function as cholesterol scavengers, extracting excess cholesterol from arterial walls and peripheral tissues. This process, termed reverse cholesterol transport, fosters the transportation of cholesterol back to the liver for excretion.
Consequently, higher levels of HDL cholesterol are associated with reduced atherosclerosis and a decreased risk of cardiovascular diseases, as they help maintain arterial integrity and mitigate the formation of atherogenic plaques.
