Engelsk definition
A minor apolipoprotein that associates with HIGH-DENSITY LIPOPROTEINS (HDL), VERY-LOW-DENSITY LIPOPROTEINS (VLDL), and CHYLOMICRONS. It regulates levels of plasma TRIGLYCERIDES by activating APOLIPOPROTEIN C-II LIPOPROTEIN LIPASE and inhibiting hepatic VLDL triglyceride hydrolysis.
