Chapter 20, Problem 2E
Summary Introduction
To identify: The products generated by the action of pancreatic lipase on the lipid shown at the top of page 665 in the text book.
Concept introduction: Pancreatic lipase is an enzyme which is also known as triacylglycerol lipase. Its enzymatic activity increases when it contacts the lipid-water interface. This phenomenon is known as interfacial activation.
