lipoprotein lipase

lipoprotein lipase
An enzyme that hydrolyzes one fatty acid from a triacylglycerol; its activity is enhanced by heparin and inactivated by heparinase. It is activated by apolipoprotein C-II; a deficiency of l. is associated with familial hyperlipoproteinemia type I. SEE ALSO: familial l. inhibitor, clearing factors, under factor. SYN: diacylglycerol lipase, diglyceride lipase.

lipo·pro·tein li·pase (lip″o-proґtēn liґpās) [EC 3.1.1.34] an enzyme of the hydrolase class that catalyzes the hydrolytic cleavage of fatty acyl groups from triglycerides (or di- or monoglycerides) in chylomicrons, very-low-density lipoproteins, and low-density lipoproteins. It occurs on capillary endothelial surfaces, especially in mammary, muscle, and adipose tissue, and requires apolipoprotein C-II as a cofactor.
