In the world of peptide research and specialized chemical analysis, precision is paramount. When evaluating specific compounds, investigators often focus on the molecular weight of palmitoyl tripeptide 1 to ensure the integrity of their experimental conditions. As someone who has spent considerable time reviewing technical data sheets and certificates of analysis for laboratory reagents, I have found that understanding the nuances of this specific peptide, often referred to as Pal-GHK, is essential for maintaining accurate research protocols.
Defining the Compound: Pal-GHK
Palmitoyl Tripeptide-1, or Palmitoyl, is a lipophilic, synthetic signal peptide. It is fundamentally composed of a short chain of three amino acids—Glycine (Gly), Histidine (His), and Lysine (Lys)—conjugated to palmitic acid. This structural modification enhances its permeability and stability in various experimental media.
When reviewing the technical specifications for this compound, you will frequently encounter the designation PalMitoyl Tripeptide, which highlights its unique lipid-bound structure. In my personal experience, ensuring the purity and accurate molar calculations is the first step in any successful assay.
The Data: Molecular Weight and Chemical Properties
One of the most common questions in the scientific community concerns the exact mass of this substance. While various databases provide slightly differing figures due to hydration states or specific salt forms, the industry standard for the Molecular Weight of Palmitoyl Tripeptide-1 is widely recognized as 578.79 g/mol.
To provide a comprehensive breakdown based on verified documentation:
* Molecular Formula: C30H54N6O5
* Standard Molecular Weight: 578.79 g/mol
* Common Variations: You may occasionally see references to Molecular Weight: 578.8 g/mol or has a molecular weight of 578.80 Da. These are rounding variations commonly found in literature.
* Alternative Data: While some sources might list an estimated 340 Da (average) for specific segments, or in r PalMitoyl Tripeptide-1 are cases, a molecular wei Its action supports skin regeneration, improving elasticity, firmness, and tone, while accelerating the healing process. ght of 560.0 G/Mol, the standard analy Purity, 98% ; Molecular Formula, C30H54N6O5 ; CAS No. 147732-56-7 ; Formula Weight, 578.79 g/mol ; Technology Applications, Promotes collagen production. tical consensus for the complete Pal-GHK molecule remains 578.79.
* Isomer Variations: It is important to note that specific CAS entries, such as 1628252-62-9, may list different values like 638.8 or 636.8661 due to different chemical configurations or derivatives.
Practical Application and Handling
When working with these substances, researchers often prepare stock solutions. For Palmitoyl Tripeptide-1 - Personal Care & Cosmetics example, you might see protocols requiring 1.7277 mL of a solvent to reach a specific molarity (such as 1 mM or 5 mM). Proper storage is equally critical; most high-purity samples are stored as a white powder at -20°C to maintain stability for up to three years.
