Which enzyme is used to hydrolyze triglycerides in kinetic enzymatic applications?

Explanation:
Lipase is the enzyme that hydrolyzes triglycerides. It specifically cleaves the ester bonds in triglycerides to form glycerol and free fatty acids. This makes it the enzyme used in kinetic studies of triglyceride breakdown, where you measure how quickly lipase converts substrate into products to determine parameters like Vmax and Km. The other enzymes have different targets: amylase acts on starch, leucine aminopeptidase trims N-terminal leucine from peptides, and lactate dehydrogenase interconverts lactate and pyruvate. None of them hydrolyze triglycerides, so lipase is the best choice for this purpose.
