•Primary structure of protein is the simplest level of protein structure.It comprises the number and sequence of amino acids in a protein molecule.

For Example:Dystrophin has an important primary structure.

•Secondary structure is formed because of hydrogen bonding between amino acids in the peptide chain.

For Example:Alpha helices and beta pleated sheets.

Tertiary structure is maintained by three types of bonds;hydrogen bond,ionic and disulphide(-S-S-).

For Example:Myoglobin

•In quaternary structure,tertiary proteins are held together by hydrophobic interactions,hydrogen and ionic bonds.

For Example:Hemoglobin

•In quaternary structure, tertiary proteins are held together by hydrophobic interactions, hydrogen, and ionic bonds.

For Example Hemoglobin

A secondary structure is formed because of hydrogen bonding between amino acids in the peptide chain, not because of the primary amino acid sequence.

For Example Alpha helices and beta-pleated sheets. 

Tertiary structure is maintained by three types of bonds; hydrogen bond, ionic, and disulfide (-S-S-) and not because of the primary amino acid sequence.

For Example Myoglobin 

Tertiary structure is maintained by three types of bonds; hydrogen bond, ionic, and disulfide (-S-S-). Only primary protein structure is because of the primary amino acid sequence.
