Question
Chapter 23, Problem 32RE
Interpretation Introduction
Interpretation:
The nature of amino acids, that is, glucogenic or ketogenic, is to be determined for the given molecules.
Concept introduction:
In catabolism, the first step involves the removal of nitrogen by the process of transamination.
The catabolic and anabolic pathways do not involve the same group of enzymes and also are not the reverse of each other.
