Chapter 24, Problem 79P

Interpretation Introduction

(a)

Interpretation:

The products should be determined which are formed when Leucine amino acid undergoes oxidative deamination with ${\text{NAD}}^{+}$ and dehydrogenase enzyme.

Concept Introduction:

Amino acids are organic compounds containing two functional groups namely amino and carboxylic group. Amino group is attached to the alpha carbon, carbon adjacent to the carbonyl group making them alpha amino acids.

  

During the catabolism of amino acids, the first step is the removal of amino group from the a-carbon and then the formation of ${\text{NH}}_4{}^{+}$ by two-step pathway namely transamination which is then followed by oxidative deamination.

Interpretation Introduction

(b)

Interpretation:

The products should be determined which are formed when Phenylalanine amino acid undergoes oxidative deamination with ${\text{NAD}}^{+}$ and dehydrogenase enzyme.
