Which type of bond forms during protein synthesis between amino acids?

• A. Hydrogen bond
• B. Ionic bond
• C. Peptide bond
• D. Covellite bond

Answer: (C)

During protein synthesis, the appropriate bond that forms between amino acids is the peptide bond. This occurs during a process called translation, where ribosomes facilitate the assembly of amino acids into a polypeptide chain based on the sequence coded in mRNA.

A peptide bond is a specific type of covalent bond that connects the carboxyl group of one amino acid to the amino group of another, releasing a molecule of water in a dehydration synthesis reaction. This bond is crucial because it provides the structural framework necessary for the formation of proteins, which are essential for various biological functions, including catalysis, signaling, and structural support.

The other types of bonds mentioned, such as hydrogen bonds and ionic bonds, may play roles in protein stability and structure once the polypeptide chain has formed, but they do not directly participate in the formation of the primary structure of proteins during protein synthesis. A covellite bond, on the other hand, is not relevant in the context of biological macromolecule formation. Thus, the peptide bond is the primary bond established between amino acids during the synthesis of proteins.
