Chapter 26.5, Problem 2QQ

Interpretation Introduction

Interpretation: To determine the number of standard amino acid carbon skeleton degradation products that are citric acid cyclic intermediates.

Concept introduction: Citric cycle is a series of eight chemical reactions used to release energy by all aerobic organisms. The acetyl part of $\text{acetyl CoA}$ is oxidized with the release of ATP and carbon dioxide.

There are 20 standard amino acids and each amino acids have different metabolic degradation pathways for their carbon skeleton and result in the production of 7 products.
