The amino acid will become more negatively charged

Explanation:

Amino acids are organic compounds containing the positive amine (-NH₂) group which is the basic group, and the negative carboxylic (-COOH) group, which is the acidic group. Because they contain both acidic and basic groups with a positive and negative charge that do not contain an overall electric charge, they are known as zwitterions. They are the smallest units of a protein molecule.

When a hydroxide group is added to an amino acid, the PH is increased, and the hydrogen ion on the amine (NH₃+) is removed, making the compound to have an overall negative charge, hence it is no longer a zwitterion.

notice that the amino group has a net negative charge on the product side of the reaction
