▼

- Circle the amine group (NH2) on either amino acid; it is the nitrogen atom bonded to two hydrogen atoms.
- Draw a triangle around the carboxyl group (COOH) on either amino acid; it is the carbon atom double-bonded to one oxygen and single-bonded to a hydroxyl group (OH).
- Each amino acid has a central (alpha) carbon bonded to an amine group, a carboxyl group, a hydrogen atom, and a variable R group.
- The R group (side chain) attached to the central carbon is different for each amino acid, determining its unique chemical properties.
