Cosmetic Peptides Palmitoyl Pentapeptides - 4 for Collagen Synthesis

Palmitoyl pentapeptide-4 (palmitoyl pentapeptide-3 before 2006) is a matrikine used in anti-wrinkle cosmetics

Palmitoyl pentapeptide-4 (Pal-Lys-Thr-Thr-Lys-Ser = Pal-KTTKS) contains 5 amino acids linked to a 16-carbon aliphatic chain for improving the penetration of the molecule through the lipid structures of the skin. It is a matrikine.

Matrikines are messenger peptides capable of regulating cell activities by interacting with their specific receptors. They activate certain genes involved in the process of extracellular matrix renewal and cell proliferation.

By activating the neosynthesis of extracellular matrix macromolecules, palmitoyl pentapeptide-4 provides an anti-wrinkle effect. Studies (in vitro and in vivo) demonstrating the anti-wrinkle efficacy of this peptide have been conducted and published by Sederma and by independent organisations.

Beauty polypeptides can penetrate the dermis to increase collagen, by rebuilding from the inside to the outside to reverse the skin aging process.

Beauty pentapeptide is a cosmetic peptides, polypeptides are prototype palmitate five peptides, known as the five peptides, can simulate the effect of botulinum toxin paralysis.

Short peptide fragments of the five amino acid by a peptide bond formation, similar to the structure of proteins, but the protein peptide chain longer, usually several hundred amino acids.

These multi-peptides containing the amino acid according to the number of different peptides can be divided into two (including two amino acids), a tripeptide (with three amino acids), four peptides (each containing four amino acids), and so on.

The different varieties because it contains amino acids , there are two different varieties of peptides, a tripeptide, too; Meanwhile, several amino acids have the same, each amino acid sequencing (link) is not the same, there will be two different peptide species.

So there have been a variety of roles now, all kinds of names polypeptide. Five peptides are composed of six amino acids (Pal- palmitic acid, Lys- lysine, Thr- threonine, Thr- threonine, Lys- lysine, Ser- serine).
