If hydroxide is added to an amino acid, how will this affect the charge on the amino acid?

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

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.
