A student is shown images of different reactions which question would help a student determine which reaction is a peptide synthesis reaction

A. Which image shows the disruption of the hydrogen bonds between Atoms in the molecules?

B. Which image shows the stabilization of the hydrogen bonds between atoms in the molecules?

C.Which image shows water as a product of the reaction between an amino acid in a car Bullock which image shows water as a product of the reaction between an amino acid and a carbonyl group?

D. Which image shows water as a reactant of the reaction between an amino acid in a carboxyl group?

The formation of a peptide bond is a condensation/dehydration reaction because a water molecule is produced during the formation of the bond. This is the case for most biolgical polymer formation from their monomers (such as glucose monomers into starch). In proteins the carbonyl group (– COOH) of one amino acid reacts with the amino group (–NH2) of the next amino acid. The carbonyl group loses an –OH while the amino group loses a –H. The OH⁻ and H⁺ combine into a water molecule.
