Which parts of the amino acids X and Y are involved in the formation of a peptide bond? (N-terminus) XY (C-terminus)

Explanation:

The amino acid is such type of the organic compound that contains one central carbon atoms and four other groups are directly connected with central carbon atoms such as one hydrogen atom, one R group, one carboxyl group, and one amino group.  

                       The carboxyl group and amino group plays an important role in the formation of the peptide bond. When the formation of a peptide bond, takes place then two amino acids are involved in which the carboxyl group of one amino acid and the amino group of other amino acids are linked to form a peptide bond.
