Chapter 26.3, Problem 5P

Interpretation Introduction

Interpretation:

A reasonable structure for the major species present in a solution of tyrosine above a $\text{pH}$ of $10$, with a net charge of $-2$ is to be suggested.

Concept Introduction:

An amino acid contains at least two functional groups, $-\text{COOH}$ and $-{\text{NH}}_{\text{2}}$, that can function as acids or bases. In addition, some amino acids may also contain functional groups on the side chain that can function as an acid or base.

The exact form (protonated/deprotonated) in which such functional groups in an amino acid exist in depends on the pH of the solution
