Oligopeptides are kinds of peptides that contains “few” amino acid units.  Usually, oligopeptides are being described as a peptide chain that contains 2 to 20 amino acid units. These include the dipeptides, tripeptides, tetrapeptides, pentapeptides, etc…

Generally, the term “oligo” is used as classifications of polymers. Peptides are one kind of polymers which can be made from chain-growth or step growth processes where its monomers, the amino acids add to the same end (or both ends) of the growing chain. Having said that, other oligopolymers such as the oligosaccharides andoligonucleotides exists.
