Whether, or not, a peptide acts as a buffer is to be checked, and the reason behind it is to be explained. Concept introduction: A peptide is a short chain of amino acid residues that are linked together by a peptide bond, formed between the alpha nitrogen atom of one amino acid, and the alpha carbon atom of the another amino acid. A buffer is a solution that resists a change in pH (potential of hydrogen) on the addition of a strong acid or base. Isoelectric point ( pI ) is the pH at which the peptide carries no net charge and remains neutral.
