Which of the following molecules is eliminated during peptide bond formation?

Step-by-step solution

Chemically, peptide linkage is an amide formed abetween –COOH group and –NH 2 group. The reaction between two molecules of similar or different amino acids, proceeds through the combination of the amino group of one molecule with the carboxyl group of the other. This results in the elimination of a water molecule and formation of a peptide bond –CO–NH–. The product of the reaction is called a dipeptide because it is made up of two amino acids. For example, when carboxyl group of glycin
