Chapter 26, Problem 26.77EP

Interpretation Introduction

Interpretation: To determine the four possible degradation products of the carbon skeletons of amino acids that function as citric acid cycle intermediates.

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.
