What is a dipeptide made of?

A dipeptide is formed when two amino acids are linked together by a peptide bond. Peptide bonds occur through a dehydration synthesis reaction, where the carboxyl group of one amino acid reacts with the amino group of another, releasing a molecule of water and resulting in a covalent bond between the two amino acids. This structure is fundamental in biochemistry, as peptides and proteins are composed of chains of amino acids, and the specific sequences and linkages dictate the properties and functions of these biological molecules. Thus, the definition of a dipeptide is clearly two amino acids bonded together.
