Description:
Apolipoprotein B (apoB) is a protein present in the blood plasma that plays a primary role in the transport and regulation of cholesterol in the human body. It is a component of low-density lipoprotein (LDL) and very low-density lipoprotein (VLDL), and is involved in transporting cholesterol and triglycerides from the liver to other tissues in the body. Levels of apoB can be measured to assess the risk of atherosclerosis and cardiovascular disease.
