Verified step by step guidance

Understand that a protein's tertiary structure is the three-dimensional shape formed by the folding of its polypeptide chain, which is stabilized by various interactions and bonds.

Recognize that peptide bonds are covalent bonds that link amino acids together in a polypeptide chain, forming the primary structure of proteins, not directly contributing to tertiary structure.

Identify that phosphodiester bonds are covalent bonds that link nucleotides together in nucleic acids, such as DNA and RNA, and are not involved in protein structure.

Acknowledge that hydrogen bonds are weak interactions that can form between polar side chains of amino acids, contributing to the folding and stability of the protein's tertiary structure.

Understand that ionic interactions, also known as salt bridges, occur between oppositely charged side chains of amino acids, further stabilizing the protein's tertiary structure.
