Chapter 27, Problem 27.31P

Interpretation Introduction

(a)

Interpretation:

The structure of phosphotyrosine residue is to be drawn.

Concept introduction:

The chemical reaction in which there is an addition of the phosphoryl group $\left({\text{PO}}_{\text{3}}^{-}\right)$ to any organic molecule is known as phosphorylation. The term, dephosphorylation is used when phosphoryl group is removed from the molecule in the reaction. These processed are carried out by enzymes.

Interpretation Introduction

(b)

Interpretation:

Whether the equilibrium constant for formation of a phosphotyrosine residue from ATP is greater than, less than, or same as $K_{\text{eq}}$ for the phosphorylation of a serine residue is to be stated.

Concept introduction:

The chemical reaction in which there is an addition of the phosphoryl group $\left({\text{PO}}_{\text{3}}^{-}\right)$ to any organic molecule is known as phosphorylation. The term, dephosphorylation is used when phosphoryl group is removed from the molecule in the reaction. These processed are carried out by an enzyme. These are the important process occurs in protein and enzymes.
