IntEnz Enzyme Nomenclature
EC 3.1.1.34

Names

Accepted name:
lipoprotein lipase
Other names:
clearing factor lipase
diacylglycerol hydrolase
diacylglycerol lipase
diglyceride lipase
lipemia-clearing factor
postheparin esterase
postheparin lipase
Systematic name:
triacylglycerol acylhydrolase (lipoprotein-dependent)

Reaction

Comments:

Hydrolyses triacylglycerols and diacylglycerol in chylomicrons and low-density lipoprotein particles (VLDL). Human protein purified from post-heparin plasma (LPL) shows no activity against triglyceride in the absence of added lipoprotein. The principal reaction sequence of that enzyme is triglyceride → 1,2-diglyceride → 2-monoglyceride. The hepatic enzyme (LIPC) also hydrolyses triglycerides and phospholipids present in circulating plasma lipoproteins.
