peptide bond

(Biochemistry) peptide linkage, bond that joins two amino acids (the carboxylic group from one acid joins with the amino group of the second creating a CONH bond)

A peptide bond is a chemical bond that is formed between two molecules when the carboxyl group of one molecule reacts with the  amino group of the other molecule, releasing a molecule of water (H2O). This is a dehydration synthesis reaction (also known as a condensation reaction), and usually occurs between amino acids. The resulting CO-NH bond is called a peptide bond, and the resulting molecule is an amide. The four-atom functional group -C(=O)NH- is called an amide group or (in the context of proteins) a peptide group.  Polypeptides and proteins are chains of amino acids held together by peptide bonds, as is the backbone of PNA.  Polyamides, such as nylons and aramids, are synthetic molecules (polymers) that possess peptide bonds.
