Explanation:
Detailed explanation-1: -In water, the ionic attractions between the ions in the solid amino acid are replaced by strong attractions between polar water molecules and the zwitterions. This is much the same as any other ionic substance dissolving in water.
Detailed explanation-2: -In alkaline conditions, the amino acid acts as an acid and donates a proton from its carboxyl group.
Detailed explanation-3: -What are Zwitterions of amino acids? A zwitterion is a compound that does not have an aggregate electrical charge, but includes different positively and negatively charged sections. The hydrogen ion is excluded from the-NH3 + group if you raise the pH of an amino acid solution by adding hydroxide ions.
