Chemistry - Biomolecules Question with Solution | TestHub

Question Explanation:

A compound containing two –COOH groups and one –NH₂ group behaves as an acidic amino acid . We determine its net charge based on ionization of these groups at pH = 14.

Concept:

This Question is based on Acid–base behavior of amino acids, Ionization of –COOH and –NH₂ groups, Net charge calculation

Solution:

The given compound is corresponds to acidic amino acids. at pH 14

Each –COOH group is deprotonated to –COO⁻ → total charge = –2
