Amino acids include a side group as well as

Amine group, carboxylic group and the hydrogen atoms.

Explanation:

Amino acids are the monomers of proteins that are linked together through the peptide bond. There are 22 standard amino acids and large number of non standard amino acids.

The structure of the amino acids includes the hydrogen atoms and the side group R contains the hydrocarbon chain. The amine group and carboxylic group are present that determines the properties of the different amino acids in the organism.

Thus, the answer is amine group, carboxylic group and the hydrogen atoms.
