Chapter 21, Problem 86E

Interpretation Introduction

Interpretation: The amino acids used in the synthesis of glutathione are to be determined.

Concept introduction: Amino acids are defined as organic compounds which contain amine $\left({\text{-NH}}_{\text{2}}\right)$ and carboxyl $\left(\text{-COOH}\right)$ functional groups, along with a side chain (R group) attached to each amino acid. When two or more amino acids are linked in a chain, a compound called peptide is formed in which the carboxyl group of each acid is joined to the amino group of the next forming a $\text{-OC-NH-}$ bond, known as peptide bond. Tripeptide is defined as a group of peptides consists of three amino acids in the molecule.

To determine: The amino acids of glutathione.
