Final answer:
Two amino acids react through a condensation reaction to form a dipeptide and water, with the creation of a peptide bond between them.
Step-by-step explanation:
When two amino acids react together to form a peptide, the products of this reaction are a dipeptide and a molecule of water. This occurs through a condensation reaction where the amino group (-NH2) of one amino acid reacts with the carboxyl group (-COOH) of another amino acid, resulting in the formation of a peptide bond (CO-NH) and the release of a water molecule (H2O). The dipeptide formed has one free amino group at one end (N-terminal) and one free carboxyl group at the other end (C-terminal), which can react with additional amino acids to extend the peptide chain into a polypeptide or eventually into a functional protein.
