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: -Primarily, the interactions among R groups creates the complex three-dimensional tertiary structure of a protein. The nature of the R groups found in the amino acids involved can counteract the formation of the hydrogen bonds described for standard secondary structures.
Detailed explanation-3: -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-4: -The tertiary structure of proteins refers to the overall three-dimensional shape, after the secondary interactions. These include the influence of polar, nonpolar, acidic, and basic R groups that exist on the protein.
Detailed explanation-5: -Once the nonpolar amino acids have formed the nonpolar core of the protein, weak van der Waals forces stabilize the protein. Furthermore, hydrogen bonds and ionic interactions between the polar, charged amino acids contribute to the tertiary structure.
