Which characteristic of an amino acid is most affected by the uniqueness of the organic side chain?
the amino acid's ability to react with other amino acids
the carboxyl group (cooh) ability to react
the central carbon atom's attachment point
the amino acid’s physical and chemical properties

Option D

Explanation:

Each and every amino acid is unique in its structure and function. This is due to the organic side chain that is different in every amino acid.

The difference in the organic side chains mostly affects the chemical and physical properties of the amino acids.

The ability to form different types of proteins is due to the difference in the amino acids side chains which adds uniqueness to the proteins.
