Lipoproteins and Cholesterol Transport

Lipoproteins are complex particles that contain cholesterol esters and triglycerides surrounded by free cholesterol, phospholipids, and apolipoproteins. They facilitate the transportation of cholesterol and triglycerides by forming a central core and interacting with proteins.

The seven classes of plasma lipoproteins are based on size, lipid composition, and apolipoproteins.

Chylomicron remnants, VLDL, IDL, LDL, and Lp (a) are pro-atherogenic, while HDL is anti-atherogenic.

<p>The four major functions of apolipoproteins are serving a structural role, acting as ligands for lipoprotein receptors, guiding the formation of lipoproteins, and serving as activators or inhibitors of enzymes involved in lipoprotein metabolism.</p> Signup and view all the answers
