In the realm of advanced peptide research, the nonapeptide stands out as a fascinating subject of study. By definition, a nonapeptide is a peptide chain of nine amino acid residues. These molecules, characterized by nine amino acid residues connected by peptide bonds, represent a diver Nonapeptide-1 acetate salt (158563-45-2 free base) se class of signaling agents found throughout biological systems. Whether exploring linear or cyclic structures, the structural precision of these peptides is what drives their specific interactions in various research applications.
The Anatomy of Nonapeptide-1
One of the most frequently discussed molecules in this category is Nonapeptide-1. Often referred to in industry literature as Melanostatine-5, it is a synthetic biomimetic peptide. When Nonapeptide-1 · L-Methionyl-L-prolyl-D-phenylalanyl-L-arginyl-D-tryptophyl-L-phenylalanyl-L-lysyl-L-prolyl-L-valinamide · L-Valinamide, L-methionyl-L-prolyl-D- analyzing the s Sequence: Met-Pro-{D-Phe}-Arg-{D-Trp}-Phe-Lys-Pro-Val-NH2. CAS No.158563-45-2 Nonapeptide-1 is one skin whitening nonapeptide. It can be applied to equence, researchers consistently identify the primary structure as Met-Pro-D-Phe-Arg-D-Trp-Phe-Lys-Pro-Val-NH2.
This specific arrangement—Met-Pro-D-Phe-Arg-D-Trp-Phe-Lys-Pro-Val—is critical to its function. The inclusion of D-amino acids (such as D-Phe and D-Trp) is a deliberate design choice that enhances the stability of the molecule. Because this compound is currently synthesized using recombinant genetic technology, laboratories can achieve high levels of purity, often exceeding 95% for solid powder formulations.
Mechanisms and Research Applications
From a research perspective, Nonapeptide-1 is primar Sequence : Met-Pro-D-Phe-Arg-D-Trp-Phe-Lys-Pro-Val Structure: Nonapeptide-1. Specifications 1. White powder : purity 95%min. 2. Nonapeptide 1 solution : 100ppm ily studied for its role as an antagonist of the α-melanocyte-stimulating hormone (α-MSH) receptor. By acting as a competitive inhibitor, Nonapeptide-1 prevents mela Nonapeptide is defined as a peptide consisting of nine amino acids, which in the context of the source, refers to bradykinin, a nonapeptide that acts as a nin synthesis by preventing the activation of tyrosinase. This makes it a significant area of focus for those investigating pathways of pigment regulation.
While the primary sequence mentioned above is the standard, it is important to note that nomenclature can vary. For instance, some literature references an alternative sequence, Arg-Arg-Asp-Ser-Tyr-Pro-Tyr-Arg-Gly, though this is distinct from the common Melanostatine-5 variant. Always verify the specific H-Met-Pro-D-Phe-Arg-D-Trp-Phe-Lys-Pro-Val-NH2 notation when sourcing materials to ensure the peptide matches your experimental requirements.
Formulations and Stability
When handling these peptides in a lab setting, one often encounters them in solution. A common sequence-ready formulation includes a base of Water, Glycerin, Nonapeptide-1, Phenoxyethanol, Ethylhexylglycerin. This combination is designed to maintain the integrity of the peptide chain.
Nonapeptide-1 is a new skin lightening biomimetic peptide that requires careful storage. Due to the sensitivity of the amide bonds, it is standard practice to keep the substance in a cool, dry environment away from moisture to prevent degradation. Whether you are working with the acetate salt or the free base, the CAS number 158563-45-2 serves as the definitive identifier Nonapeptides and the Evolutionary Patterning of Sociality - PMC for this specific peptide.
Beyond Synthetic Variants: The Broader Family
It is essential to recognize that Nonapeptides are an ancient family of neuropeptides. Beyond the synthetic versions used in cosmetic research, nature provides numerous examples, such as oxytocin and arginine vasopressin. These molecules play vital roles in the evolutionary patterning of sociality across diverse species.
By understanding the difference between these naturally occurring neuropeptides and synthetic derivatives, researchers can better appreciate the versatility of the nonapeptide class. Whether you are investigating the structural properties of Met-Pro-D-Phe-Arg-D-Trp-Phe-Lys-Pro-Val-NH2 or exploring the broader evolutionary significance of these nine-residue chains, the precision of the sequence remains the cornerstone of all biochemical inquiry.
