Question

Which type of bond is found between amino acids in a protein chain?

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

Hint:

Amino acids are linked by peptide bonds. Without peptide bonds, proteins wouldn’t exist!

Answer 1

The Correct Option is B

Peptide bonds are covalent bonds that link amino acids together in a protein chain. A peptide bond is formed during a dehydration synthesis reaction where the carboxyl group (-COOH) of one amino acid reacts with the amino group (-NH2) of another amino acid. This results in the release of a water molecule and the formation of the bond between the two amino acids. Peptide bonds are the fundamental link that holds together the primary structure of proteins. As the chain of amino acids grows, it folds into complex shapes, determining the protein's final structure and function.
