the findings indicate that lipoprotein lipase in heart is synthesized by myocytes , transferred across extracellular space along cell surfaces and across endothelial cells via vesicles or intracellular channels , and concentrated at the surface of luminal projections of endothelium where the enzyme hydrolyzes triacylglycerol of chylomicrons and very low-density lipoproteins .
