How high density lipoprotein(hdl) play a role in fats in body?

Complicated molecule: Hdl-c is more than a scavenger particle of cholesterol in blood vessels. It has antioxidant, anti-inflammatory, thrombotic characteristics as well. There are families of hdl, not all of which may be beneficial. Plus, HDL may change in the circulation depending on active disease states. It also exchanges triglycerides & bad cholesterol in the circulation for disposal. Treatment benefit unknown.

Remove Fat from Cell: Hdl particles, the smallest & highest density (compared to surrounding water), of the lipoproteins, with alpha, not beta, lipoprotein, as their key structure organizing protein, form as small flat disks. Hdl is potentially able to remove fat from cells overloaded with intracellular fat, including from white blood cells in the walls of arteries before they die, thus helping prevent atherosclerosis.
