Amino acids and their functional groups
An amino acid is an organic molecule containing both an amine functional group, -NH2\text{-NH}_2-NH2, and a carboxylic acid functional group, -COOH\text{-COOH}-COOH. A functional group is an atom or group of atoms that determines the characteristic chemical reactions of an organic compound.
