Protein structure depends on its amino acid sequence and local, low-energy chemical bonds between atoms in both the polypeptide backbone and in amino acid side chains. Protein structure plays a key role in its function, if a protein loses its shape at any structural level, it may no longer be functional. Primary structure is the amino acid sequence. Secondary structure is local interaction between stretches of a polypeptide chain and includes $α$ -helix and $β$ pleated sheet structures. Tertiary structure is the overall three-dimension folding driven largely by interactions between $R$ groups. Quaternary structures is the orientation and arrangement of subunits in multi-subunit proteinThe primary structure of a protein molecule has
