Which of the Following Forces are Involved in Maintaining the Primary

Question

Which of the following forces are involved in maintaining the primary structure of a protein?
A) covalent bonds
B) hydrogen bonds
C) ionic interactions
D) hydrophobic interactions

Accepted Answer

Covalent bonds between amino acids are involved in maintaining the primary structure of a protein. The primary structure refers to the sequence of amino acids in the polypeptide chain. Covalent bonds form between the carboxyl group of one amino acid and the amino group of the next amino acid, forming peptide bonds that link the amino acids together in a linear chain. Hydrogen bonds, ionic interactions, and hydrophobic interactions are involved in maintaining the secondary, tertiary, and quaternary structures of proteins, but not the primary structure.
