ApoC-III, or Apolipoprotein C-III, is a protein that plays a crucial role in lipid metabolism. It is primarily found in lipoproteins, which are particles that transport fats in the bloodstream. ApoC-III is known to inhibit the breakdown of triglycerides, leading to increased levels of these fats in the blood. Elevated levels of ApoC-III are associated with various metabolic disorders, including hyperlipidemia and cardiovascular disease. Research suggests that targeting ApoC-III could be a potential strategy for treating these conditions, as reducing its levels may help improve lipid profiles and overall heart health.
