Chapter 26.5, Problem 3QQ

Interpretation Introduction

Interpretation: To identify the incorrect statement concerning the genicity of standard amino acid degradation products.

Concept introduction: Genicity of an amino acid is defined as whether the carbon skeleton degradation product of an amino acid can produce glucose or ketone bodies or not.

There are 20 standard amino acids and each has a different carbon skeleton. An amino acid is known as a glucogenic amino acid if its carbon-containing degradation product can be used to produce glucose. An amino acid is known as a ketogenic amino acid if its carbon-containing degradation product can be used to produce ketone bodies.
