Concept explainers
(a)
To determine: The net charge of carnosine at pH 3.
Concept introduction: The amino acid in free form has different charges than the amino acid present in a group or polypeptide chain. Each amino acid has unique ionization characteristics that vary at different pH.
(b)
To determine: The net charge of carnosine at pH 5.
Concept introduction: The amino acid in free form has different charges than the amino acid present in a group or polypeptide chain. Each amino acid has unique ionization characteristics that vary at different pH.
(c)
To determine: The net charge of carnosine at pH 7.
Concept introduction: The amino acid in free form has different charges than the amino acid present in a group or polypeptide chain. Each amino acid has unique ionization characteristics that vary at different pH.
(d)
To determine: The net charge of carnosine at pH 9.
Concept introduction: The amino acid in free form has different charges than the amino acid present in a group or polypeptide chain. Each amino acid has unique ionization characteristics that vary at different pH.
