Primary structure of a protein includes number of polypeptides, number and sequence of amino acids in each polypeptide.

The development of new stearic relationships of amino acids present in linear sequence inside the polypeptides leads to the formation of secondary structure of proteins.

Tertiary structure involves interactions that are caused by binding and folding of a-helix or P sheets leading to the formation of rods, spheres or fibres. Tertiary structure is stabilized by several types of bonds such as, H-bonds, ionic bonds, covalent bonds, van der Waal’s interactions hydrophobic bonds, etc.
