The protein structures can be classified into four levels, namely the primary structure, secondary structure, tertiary structure, and quaternary structure. The primary structure is the simplest of all the structures.

In this structure, the a carbon atom is bonded to hydrogen atom, carboxyl group, amino group, and an 'R' group.
