Concept introduction:

Proteins are biomolecules that are composed of certain monomer units such as amino acids. These are carboxylic acids with one amino group bonded on the alpha-C atom of the molecule. These amino acids involve in condensation process to form peptides and polypeptides which further form complex protein molecules. Amino acids are the organic molecules with both ${\text{–NH}}_{\text{2}}$ and $\text{–COOH}$ groups functional groups bonded on the same C atom of the molecule.
