Detailed explanation-1: -The overall three-dimensional structure of a polypeptide is called its tertiary structure. The tertiary structure is primarily due to interactions between the R groups of the amino acids that make up the protein.

Detailed explanation-2: -Tertiary structure is the most important of the structural levels in determining, for example, the enzymatic activity of a protein.

Detailed explanation-3: -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.

Detailed explanation-4: -Tertiary structure is the next level up from the secondary structure, and is the particular three-dimensional arrangement of all the amino acids in a single polypeptide chain. This structure is usually conformational, native, and active, and is held together by multiple noncovalent interactions.
