Triacylglycerol lipase
The enzyme triacylglycerol lipase (also triglyceride lipase, EC 3.1.1.3;systematic name triacylglycerol acylhydrolase) catalyses the hydrolysis of ester linkages of triglycerides:[1]
- triacylglycerol + H2O ⇌ diacylglycerol + a carboxylate

These lipases are widely distributed in animals, plants and prokaryotes. This family was also called class 3 lipases as they are only distantly related to other lipase families.[2][3][4][5][6]
