The bond formed between two amino acids is called a peptide bond.

Here's how it works:

* Amino acids have a central carbon atom bonded to an amino group (NH2), a carboxyl group (COOH), a hydrogen atom (H), and a side chain (R).

* Peptide bond formation occurs when the carboxyl group of one amino acid reacts with the amino group of another amino acid.

* This reaction releases a molecule of water (H2O) and forms a peptide bond (CO-NH).

This process can continue, linking many amino acids together to form a polypeptide chain. Polypeptide chains can then fold into complex three-dimensional structures to form proteins.
