Here's a bit more detail:

* Peptide bonds are formed through a dehydration reaction, where a molecule of water is removed.

* The carboxyl group (-COOH) of one amino acid reacts with the amino group (-NH2) of another amino acid.

* This creates a covalent bond between the carbon atom of the carboxyl group and the nitrogen atom of the amino group.

* The resulting molecule is a dipeptide.

* Chains of amino acids linked by peptide bonds are called polypeptides.
