Clinical Significance

Not only is apo C-III a key regulator in the metabolism of triglycerides, but it is also an independent risk factor for CVD. Not only does apo C-III contribute to CVD through the regulation of triglycerides but also through its direct atherogenic effects, promoting atherosclerosis (fig 1) 1.

Physiological Significance

Apo C-III is composed of 79 amino acids and has a molecular weight of 8.8kDa. Apo C-III promotes hypertriglyceridemia via several mechanisms. Firstly, like apo C-II, apo C-III also inhibits the activity of LPL, distributing lipid lipolysis. Apo C-III hinders the binding of apolipoprotein B and apolipoprotein E to the hepatic receptors resulting in the delayed catabolism of triglyceride – rich lipoproteins (TRLs). Finally, apo C-III prefers the production and secretion of very low-density lipoproteins (VLDL) in the liver 1.
