What Are Peptides?

Peptides are short chains of amino acids linked together by peptide bonds. They are smaller than proteins — typically fewer than about 50 amino acids — but built from the same fundamental units.

In the human body, peptides occur naturally and participate in a wide variety of biological roles. Because of their size and structure, they sit between individual amino acids and larger, more complex proteins.
