Chapter 24, Problem 24.58E

Interpretation Introduction

(a)

Interpretation:

To classify whether aspartate is glucogenic or ketogenic amino acid based on its conversion product.

Concept introduction:

The degradation of amino acids takes place in two steps. First step is the removal of amino group by the oxidative deamination and after that degradation of carbon skeleton is done. The catabolism of remaining carbon skeleton can be done into various products. Those various products can be pyruvate, acetyl CoA and acetoacetyl CoA.

Interpretation Introduction

(b)

Interpretation:

To classify whether leucine is glucogenic or ketogenic amino acidbased on its conversion product.
