A peptide bond, also known as a peptide linkage, is an amide formed between the -COOH group and -NH₂ group of amino acids. It is created through a reaction between the amino group of one amino acid and the carboxyl group of another, resulting in the elimination of water.

A peptide bond is a covalent bond formed between the carboxyl group of one amino acid and the amino group of another, resulting in the linkage of two amino acids. This condensation reaction involves the removal of a water molecule and is catalyzed by ribosomes during protein synthesis. The carbon-nitrogen bond forms between the α-carbon of the carboxyl group and the nitrogen of the amino group. The resulting structure is a dipeptide, and the repeating formation of such bonds forms polypeptide chains, constituting the backbone of proteins. Peptide bonds provide stability and structural integrity to proteins.
