A peptide bond (amide bond) is a covalent chemical bond formed between two amino acid molecules.ne loses a hydrogen and oxygen from its carboxyl group (COOH) and the other loses a hydrogen from its amino group (NH 2). This reaction produces a molecule of water (H 2 O) and two amino acids joined by a peptide bond (-CO-NH-).
Key Points Summary. 1  Proteins are made up of amino acids which determine the types of bonding and interaction they can take part in. 2  Amino acids form non-covalent bonds between themselves and other molecules, such as Hydrogen bonds, charge-charge interactions, Van der Waals forces or hydrophobic interactions.
