Oligopeptide
Oligopeptide — A short peptide consisting of 2 to 20 amino acid residues, smaller than a polypeptide but larger than a single amino acid.
What Is an Oligopeptide?
An oligopeptide is a short peptide containing approximately 2-20 amino acid residues. The prefix "oligo-" (Greek for "few") distinguishes these from longer polypeptides. Most synthetic research peptides, including ipamorelin (5 residues), GHRP-6 (6 residues), and oxytocin (9 residues), are oligopeptides.
Properties
- Structure: Generally too short for stable tertiary structure without constraints (disulfides, cyclization)
- Synthesis: Efficiently produced by SPPS with high yields
- Analysis: Easily characterized by MS and HPLC
