Chapter 19, Problem 19.68P
Interpretation Introduction

Interpretation:

The reason is to why ammonia is required in excess amounts in the preparation of amino acids to be predicted.

Concept introduction:

Proteins on hydrolysis are broken down into smaller fragments known as amino acids. They are required by the human body for various chemical purposes. Amino acids can be prepared by using different methods of synthesis like amination of α-halocarboxylic acids, Strecker synthesis, by using pthalamide salt, etc.
