Chapter 26, Problem 26.111EP

Interpretation Introduction

Interpretation: To explain how the carbon atoms from amino acids can end up in ketone bodies.

Concept introduction: Amino acids are the main building blocks of proteins. Amino acids that participate in peptide bond synthesis in proteins are known as standard amino acids.

There are 20 standard amino acids and each amino acids have different metabolic degradation pathways for their carbon skeleton. Fates of degradation of the carbon skeletons of different amino acids are as below:
