# Where does a chemical bond form when a dipeptide is synthesized?

The peptide bond between two amino acids forms between the carbon of the carboxylic acid on the carboxyl end, and the nitrogen of the amino group on the amino end. The peptide bond is a $\text{C"-"N}$ bond.
The formation of a dipeptide (or polypeptide) is a dehydration synthesis in which one molecule of water is formed by the $\text{OH}$ group on the carboxyl end and the $\text{H}$ atom of the next amino acid on the amino end. One molecule of water is removed for every two amino acids that form a peptide bond.
