AI overview

A peptide is a short chain of amino acids, the basic building blocks that make up proteins. Peptides are important in biology because they perform many critical functions in living organisms, such as fighting infections and regulating body processes.

Peptides are short chains of amino acids linked by peptide bonds. A polypeptide is a longer, continuous, unbranched peptide chain. Polypeptides that have a molecular mass of 10,000 Da or more are called proteins. Chains of fewer than twenty amino acids are called oligopeptides, and include dipeptides, tripeptides, and tetrapeptides. Proteins are polypeptides, i.e. large peptides.
