Detailed explanation-1: -Tertiary structure-the three-dimensional structure of a protein-is the next level of complexity in protein folding.

Detailed explanation-2: -The next level of protein structure, secondary structure, refers to local folded structures that form within a polypeptide due to interactions between atoms of the backbone.

Detailed explanation-3: -Tertiary structure refers to the three‐dimensional arrangement of all the atoms that constitute a protein molecule. It relates the precise spatial coordination of secondary structure elements and the location of all functional groups of a single polypeptide chain.

Detailed explanation-4: -The sequence of amino acids in a protein is called its primary structure. The secondary structure is determined by the dihedral angles of the peptide bonds, the tertiary structure by the folding of protein chains in space.

Detailed explanation-5: -Protein tertiary structure is the three dimensional shape of a protein. The tertiary structure will have a single polypeptide chain “backbone” with one or more protein secondary structures, the protein domains. Amino acid side chains may interact and bond in a number of ways.
