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: -The tertiary structure of a protein refers to the overall three-dimensional arrangement of its polypeptide chain in space. It is generally stabilized by outside polar hydrophilic hydrogen and ionic bond interactions, and internal hydrophobic interactions between nonpolar amino acid side chains (Fig.
Detailed explanation-3: -Tertiary structure-the level of protein structure at which an entire polypeptide chain has folded into a three-dimensional structure. In multi-chain proteins, the term tertiary structure applies to the individual chains.
Detailed explanation-4: -The tertiary structure of a protein molecule encompasses the overall folding of polypeptide chains, where, if more than one chain is present, the chains are linked by covalent bonds-most often disulfide bonds (as in II).
Detailed explanation-5: -Tertiary structure refers to the overall folding of the entire polypeptide chain into a specific 3D shape. The tertiary structure of enzymes is often a compact, globular shape.
