Question
Chapter 23.3, Problem 3QC
Summary Introduction
To review:
The importance of removing the amino group from amino acid during its catabolism.
Introduction:
Amino acid is the basic unit of a protein. It is composed of the amino group, the carboxylic group, and the carbon side chain. Proteins are obtained from the diet and catabolized by the digestive tract. The amino acids thus obtained are transferred to the bloodstream.
