What Is a Pentapeptide?
A pentapeptide is a peptide consisting of five amino acid residues. Pentapeptides are small enough for efficient chemical synthesis and oral absorption potential, yet large enough to achieve meaningful target recognition. Several commercially important peptides are pentapeptides.
Notable Pentapeptides
- Leu-enkephalin: YGGFL. Endogenous opioid pentapeptide
- Met-enkephalin: YGGFM. Endogenous opioid pentapeptide
- Thymopentin (TP-5): RKDVY. Thymus-derived immunomodulatory peptide
- Matrixyl (Palmitoyl-KTTKS): Collagen-stimulating cosmeceutical pentapeptide
