Questions: 10. Where does the peptide bond occur?

The peptide bond occurs between the carboxyl group of one amino acid and the amino group of another amino acid. This bond forms through a dehydration synthesis reaction, where a molecule of water is released as the bond is created. Specifically, the carboxyl group (–COOH) of one amino acid reacts with the amino group (–NH2) of another, resulting in the formation of a covalent bond known as a peptide bond (–CO–NH–).

In summary, the peptide bond occurs between the carboxyl group of one amino acid and the amino group of another amino acid.
