What is Apolipoprotein B(ApoB)? What role does it play in the body?Updated 7 months ago

Apolipoprotein B (ApoB) is a structural protein, found on all potentially atherogenic ( plaque-forming) particles. ApoB is the main protein found in low-density lipoproteins (LDL). Like other lipoproteins (LDL and HDL), ApoB is responsible for transporting cholesterol throughout the body. It’s critical that cholesterol gets transported because cholesterol is needed to produce the hormones that are important for cellular health and function.

 

Because ApoB-tagged particles carry LDL cholesterol and other plaque-forming cholesterol markers, elevated ApoB levels can indicate that the body cannot clear excess LDL cholesterol from the blood. Elevated cholesterol levels restrict blood flow and increase cardiovascular disease risk.

 

The biomarker ApoB provides a direct measure of the number of potentially plaque-forming and artery-blocking particles in the bloodstream. This is why it’s now seen as one of the most essential indicators of heart health and heart disease risk. ApoB is now included in the Ultimate plan with InsideTracker.
