When exploring the world of advanced cosmetic ingredients, one name consistently surfaces in high-performance formulations: Palmitoyl Pentapeptide-4. For those of us who prioritize ingredient integrity in our personal care routines, understanding the structural composition of this molecule is essential. Often recognized by its commercial designation, Matrixyl, this bioactive compound has earned its reputation as a cornerstone in topical aesthetics.
Decoding the Chemical Structure
The effectiveness of this ingredient lies in its specific sequence. Biochemically, it is a synthetic peptide where a palmitoyl group—a long-chain fatty acid—is chemically linked to a pentapeptide sequence. This lipophilic Sequence: Pal-Lys-Thr-Thr-Lys-Ser-OH, Pal-KTTKS Palmitoyl pentapeptide 4 KTTKS ; Function: Palmitoyl Pentapeptide‑4, often known by its commercial name Matrixyl, modification is crucial because it enhances the molecule's Palmitoyl Pentapeptide-4. Article No.: 2542100. Product Group: Cosmetic Product. Sequence: Pal-Lys-Thr-Thr-Lys-Ser (Pal-KTTKS). Product form: Lyophilized Powder. ability to interact with the skin's surface, improving overall delivery and efficacy.
The primary amino acid string defining this Palmitoyl Pentapeptide-4 is lysine-threonine-threonine-lysine-serine. In scientific literature and technical data sheets, you will frequently see this represented as Pal-Lys-Thr-Thr-Lys-Ser-OH or the abbreviated form, Pal-KTTKS.
Key technical specifications include:
* CAS Number: 214047-00-4
* Molecular Formula: C39H75N7O10
* Molecular Weight: Approximately 802.05 g/mol
* Standard Nomenclature: Pal-Lys-Thr-Thr-Lys-Ser
Biological Signaling and Function
Why is this specific Palmitoyl Pentapeptide so highly regarded? It functions as a "signal peptide." Research suggests that it acts as a precursor sequence fragment of type I collagen. By mimicking the structure of natural skin components, it stimulates collagen production, which is why it is widely celebrated for its role in promoting skin health and rejuvenation.
It is important to note that while the standard Palmitoyl Pentapeptide-4 is associated with the KTTKS sequence, some studies indicate it is associated with two sequences, KTTKS and KTSKS, depending on the specific synthesis profile. This versatility highlights why it is a synthetic cosmetic ingredient widely used in skincare products across the globe.
