1. A dipeptide or polypeptide: This is the primary product, consisting of two or more amino acids linked together by a peptide bond.

2. Water (H₂O): This is a byproduct of the reaction, formed when the hydroxyl group (OH) from the carboxyl group of one amino acid and a hydrogen atom (H) from the amino group of the other amino acid are removed.

The overall reaction can be represented as:

Amino acid 1 + Amino acid 2 → Dipeptide + Water

Specifically:

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

* A molecule of water is released as a byproduct.

* The remaining carbon atom of the carboxyl group and the nitrogen atom of the amino group form a covalent bond, known as a peptide bond.

This process is catalyzed by ribosomes in cells, and it forms the basis for protein synthesis.
