Lipoproteins are particles comprised of protein and lipids, with a core of triglycerides and cholesterol esters and an outer layer of phospholipids.
Lipoproteins transport lipids through the bloodstream.
LDL-lipoproteins carry cholesterol from the liver to the body tissues. HDL- lipoproteins carry cholesterol back to the liver from the body tissues.
LDL-lipoproteins also bind and transport Coenzyme Q10 molecules, predominately in their reduced form, from the absorption cells in the small intestine through the lymph and the blood to the tissues.
Coenzyme Q10 helps to prevent the peroxidation of lipoprotein lipids in the blood circulation.Littarru, Gian Paolo, M.D., Ph.D.: Dr. Littarru was a post-doctoral fellow at Dr. Folkers’ Institute for Biomedical Research and then a professor of biochemistry at the University of Ancona Medical School (Italy). His primary research interest was Coenzyme Q10 in its role in bio-energetics, in its role as a fat-soluble antioxidant, and in its effect on endothelial function.
