Peptide bond formation

A peptide bond forms when the amino group of one amino acid reacts with the carboxyl group of another, releasing a water molecule in a process called a condensation reaction. This creates a strong covalent bond between the carbon atom of the carboxyl group and the nitrogen atom of the amino group. Peptide bonds link amino acids together in chains, producing proteins. This bond is stable but can be broken down through specific processes, enabling the building and remodeling of proteins essential for biological functions.
