In the evolving field of biochemical research and cosmetic formulation, the term "tripeptide" frequently appears, often linked to specific CAS (Chemical Abstracts Service) numbers. As a user interested in the structural nuances of amino acid chains, I have spent significant time investigating these compounds. A tripeptide is a peptide derived from three amino acids joined by two or sometimes three peptide bonds. Understanding these structures is essential for anyone looking into advanced biochemical research or high-end formulation development.
Exploring Key CAS Tripeptide Identifiers
When research Jun 28, 2025 — Tripeptide-29 (collagen tripeptide, CAS: 2239-67-0) is a synthetic peptide composed of glycine, proline, and hydroxyproline-key structural ing these compounds, the CAS registry is the gold standard for identification. Because a tripeptide is a peptide derived from three amino acids joined by two or sometimes three peptide bonds, specificity in naming is vital.
* Tripeptide-1 (CAS No. 72957-37-0): This is perhaps the most well-known entity. Tripeptide-1 is a small peptide composed of three amino acids (glycine-histidine-lysine or GHK). It is recognized for its role in cellular communication studies.
* Tripeptide-29 (CAS: 2239-67-0): Often referred to as a collagen pre-peptide, this compound is a synthetic peptide consisting of glycine, proline, and hydroxyproline. It is a prepeptide topical collagen with a molecular weight of 250D, which makes it a frequent subject of study regarding absorption efficiency.
* Palmitoyl Tripeptide-1 (CAS No. 147732-56-7): This is a modified version synthesized via stepwise peptide synthesis, often utilized in formulations targeting skin health.
* Tripeptide-32 (CAS 1185583-20-3): Also known as Chronolux, Tripeptide-32 is a synthetic tripeptide composed of three amino acids: proline, serine, and threonine. It is a bioactive peptide recognized for its propertie Tripeptide s in cosmetic research.
Practical Applications and Research Trends
The versatility of these compounds extends from cosmetic formulations to advanced biochemical investigations. For instance, Tripeptide-29 is a small, naturally occurring amino-acid peptide that serves as one of the primary building blocks for collagen protein. Because it is designed for use in cosmetic formulations targeting skin care applications, the purity of the CAS 2239-67-0 material is a critical priority for formulators.
Similarly, Tripeptide-1 is a synthetic peptide that has garnered attention for its involvement in type I collagen fragment studies. When looking for a CAS tripeptide for sale, it is important to verify the sequence and the molecular weight to ensure it meets the requirements of your specific project.
Broader Context: Peptides in Science
The landscape of peptide research is vast. Beyond simple tripeptides, the industry is seeing significant advancements in complex chains. For example, Tirzepatide (CAS 2023788-19-2) represents a much larger, linear peptide containing 39 ami Tripeptide-29 For Sale (200mg) no acids, often discussed in the context of emerging therapeutic researc Tripeptide-1 is a small peptide composed of three amino acids (glycine-histidine-lysine or GHK) and is known for type I collagen fragments. h. While tripeptides remain t Safety Assessment of Tripeptide-1, Hexapeptide-12, their he focus of localized, topical, or cellular studies, the progress in synthesizing these chains is improving treatments for cancer, inflammatory and infectious diseases.
Final Observations
Whether you are looking for a specific CAS tripeptide to support your biochemical research or exploring the structural benefits of Tripeptide-29 (CAS 2239-67-0), the key is to prioritize high-purity sources. My personal experi Tripeptide-29 - SID 440235153 - PubChem - NIH ence has shown that when you use a high-quality, verified peptide, the consistency in experimental or formulation outcomes is significantly higher.
Always ensure that you are referencing the correct CAS number, as even minor variations in amino acid sequences—such as those found in Tri-aspartic acid (CAS No. 107208-63-9)—result in vastly different chemical properties. By The tripeptide glutathione (GSH), which plays an important role in the maintenance of the intracellular thiol redox state and in detoxification processes. focusing on the structural integrity of these three-amino-acid chains, one can better appreciate the role they play in modern science and cosmetic ingredient technology.
