5 Questions
What are lipoproteins and how do they facilitate the transportation of cholesterol and triglycerides?
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.
What are the seven classes of plasma lipoproteins based on?
The seven classes of plasma lipoproteins are based on size, lipid composition, and apolipoproteins.
Which lipoproteins are pro-atherogenic and which one is anti-atherogenic?
Chylomicron remnants, VLDL, IDL, LDL, and Lp (a) are pro-atherogenic, while HDL is anti-atherogenic.
What are the four major functions of apolipoproteins?
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.
What is the exogenous lipoprotein pathway and how does it start?
The exogenous lipoprotein pathway starts with the incorporation of dietary lipids into chylomicrons.
