Comment |
Hydrolyses triacylglycerols and diacylglycerol in chylomicrons and low-density lipoprotein particles. 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.
