Detailed explanation-1: -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-2: -The tertiary structure of a protein consists of the way a polypeptide is formed of a complex molecular shape. This is caused by R-group interactions such as ionic and hydrogen bonds, disulphide bridges, and hydrophobic & hydrophilic interactions.
Detailed explanation-3: -The tertiary structure of a protein is formed through different types of interactions, such as hydrogen bonding, disulfide bonds, and hydrophobic interactions. Hydrogen bonds form between polar hydrogen atoms and other polar molecules, such as amine groups, alcohol groups, and acids.
Detailed explanation-4: -Four interactions stabilize the tertiary structure of a protein: (a) ionic bonding, (b) hydrogen bonding, (c) disulfide linkages, and (d) dispersion forces.
Detailed explanation-5: -A peptide bond. This covalent bond forms when the carbon atom from the carboxyl group of one amino acid shares electrons with the nitrogen atom (blue) from the amino group of a second amino acid.
