Isomer-specific effects of conjugated linoleic acid on HDL functionality associated with reverse cholesterol transport.

High-density lipoproteins (HDLs) are atheroprotective because of their role in reverse cholesterol transport. The intestine is involved in this process because it synthesizes HDL, removes cholesterol from plasma and excretes it into the lumen. We investigated the role of selected dietary fatty acids on intestinal cholesterol uptake and HDL functionality.
