Chapter 25, Problem 25.39AP

Interpretation Introduction

(a)

Interpretation:

The phosphate of ATP that undergoes the nucleophilic hydroxy group of ribose-5-phosphate is to be identified and the by-product of the reaction is to be given.

Concept Introduction:

PRPP is an important intermediate in the biosynthesis of nucleic acids and amino acids. It reacts with nucleophiles at carbon-1 in typical SN2 type of reaction.

Interpretation Introduction

(b)

Interpretation:

The reaction of ammonia with PRPP with correct stereochemistry, is to be determined.

Concept introduction:

The lone pairs on nitrogen in ammonia will attack on the carbon atom resulting in the formation of a new carbon-nitrogen bond. Simultaneously, the bond between carbon and the oxygen atom in pyrophosphate breaks.

Interpretation Introduction

(c)

Interpretation:

The other biochemical reaction which ensures that the reaction of ammonia with PRPP goes to completion is to be determined.

Concept introduction:

The irreversible last step in the reaction sequence drives the reaction to completion.
