(a)
To determine: The net charge of the predominant form of Arg 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 Arg at pH 5.0.
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 Arg at pH 10.5.
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 Arg at pH 13.5.
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.
