Chapter 22.6, Problem 20P

(a)

Interpretation Introduction

Interpretation:

The amino acids obtained from the reductive amination of given metabolic intermediates inside a cell should be given.

Concept introduction:

Reductive amination of α-keto acids synthesize amino acids, in which conversion of α-keto group into an amine group is taking place.

In cells, some enzymes carry out this conversion of α-keto acids into amino acids. Here, only the D-amino acids are formed.

(b)

Interpretation Introduction

Interpretation:

The amino acids that are obtained from the reductive amination of given metabolic intermediates in the laboratory should be given.

Concept introduction:

Reductive amination of α-keto acids synthesize amino acids, in which conversion of α-keto group into an amine group is taking place.

In laboratory, racemic mixture (both D and L-amino acids in equal amounts) of amino acids are formed.
