In the evolving field of biochemical research and cosmetic formulation, the term "tripeptide" frequently appears, often linked to specific CAS (Chemical Abstract Tripeptide s 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.

When researching these compounds, the CAS registry is the gold standard for identification. Becaus Safety Assessment of Tripeptide-1, Hexapeptide-12, their e 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 u Apr 23, 2014 — Palmitoyl tripeptide-1 (CAS No. 147732-56-7) is synthesized via stepwise peptide synthesis.3 The C- terminal amino acid (Lys) is protected on tilized 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 properties 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 Jun 28, 2025 — Tripeptide-29 (collagen tripeptide, CAS: 2239-67-0) is a synthetic peptide composed of glycine, proline, and hydroxyproline-key structural chains. For example, Tirzepatide (CAS 2023788-19-2) represents a much larger, linear peptide containing 39 amino acids, often discussed in the context of emerging therapeutic research. While tripeptides remain the 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 Tripeptide-1 is a small peptide composed of three amino acids (glycine-histidine-lysine or GHK) and is known for type I collagen fragments. -29 (CAS 2239-67-0), the key is to prioritize high-purity sources. My personal experience 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 correc Approval Year ; CAS. 1169946-69-3, PRIMARY ; FDA UNII. 08538PJ2XV, PRIMARY t 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 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.
