Study Notes
Lipoprotein Complexes
- HDL (High-Density Lipoprotein) is primarily responsible for transporting cholesterol from peripheral tissues back to the liver.
Apolipoproteins
- Apolipoprotein B-48 is primarily associated with chylomicrons.
Lipoprotein Synthesis
- Most lipoprotein complexes are produced in the liver and intestine.
Lipoprotein Complexes and Triglyceride Transport
- VLDL (Very-Low-Density Lipoprotein) is primarily responsible for transporting endogenous triglycerides to peripheral tissues.
- Chylomicrons are mainly responsible for transporting dietary triglycerides from the intestine to peripheral tissues.
Lipoprotein Composition
- LDL (Low-Density Lipoprotein) has the highest percentage of cholesterol esters.
Apolipoproteins and LDL
- Apolipoprotein A-1 is NOT associated with LDL.
Lipoprotein Synthesis Location
- Most lipoprotein complexes are synthesized in the liver and intestine.
Exogenous Triglyceride Transport
- Chylomicrons primarily transport exogenous triglycerides to peripheral tissues.
Reverse Cholesterol Transport
- HDL (High-Density Lipoprotein) plays a significant role in reverse cholesterol transport.

Description
Test your knowledge of lipoprotein metabolism with this quiz. Learn to distinguish between major lipoprotein complexes such as chylomicrons, VLDL, LDL, HDL, and Lp(a), and recognize their make-up and associated apolipoproteins. This quiz is based on Dr. Reem Sallam's lecture on biochemistry and molecular biology.
