Chapter 19, Problem 19.82QP

Interpretation Introduction

Interpretation:

The benefit obtained from covalent modification of triacylglycerol lipase by phosphorylation has to be determined.

Concept Introduction:

There are various methods of regulation of enzymatic activity such as feedback inhibition, usage of allosteric enzymes, synthesis of proenzymes, and covalent modification of a protein.

The method of protein modification is often achieved either via phosphorylation that activates the enzyme as in the case of lipase or dephosphorylation that deactivates the enzyme.
