Concept explainers
To draw: The structure of ATLDAK.
Concept introduction: Each amino acid has unique ionization characteristics that vary at different pH. Ionizable groups such as amino group, carboxylic group at certain pH remain protonated and when the pH increases, it becomes deprotonated. The isoelectric point is the pH at which net electric charge of a molecule is zero.

(b)
To determine: The net charge of ATLDAK at pH 7.0.
Concept introduction: Each amino acid has unique ionization characteristics that vary at different pH. Ionizable groups such as amino group, carboxylic group at certain pH remain protonated and when the pH increases, it becomes deprotonated. The isoelectric point is the pH at which net electric charge of a molecule is zero.
