(a)
To determine: The net charge of the predominant form of Asp at pH 1.0.
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.
(b)
To determine: The net charge of the predominant form of Asp at pH 3.0.
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.
(c)
To determine: The net charge of the predominant form of Asp at pH 6.0.
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.
(d)
To determine: The net charge of the predominant form of Asp at pH 11.0.
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.
