In the realm of biochemica Tyrosine is the only major, natural nutrient containing an aromatic hydroxyl group. Derivatives of tyrosine dipeptide can be regarded as diphenols. l research, the study of small molecular chains has become increasingly significant. Among these, the dipeptide Phe Tyr—a sequence formed from L-phenylalanine and L-tyrosine residues—stands out due to its unique chemical architecture. As someone deeply interested in the molecular building blocks used in laboratory settings, I have spent significant time examining how these specific sequences, often referred to as FY dipeptide or Phe-Tyr, behave in controlled environments.
Chemical Composition and Classification
The molecular structure of this compound, represented by the molecular formula C18H20N2O4, defines its role in various applications. It is essential to recognize that phenylalanine and tyrosine are both aromatic amino acids, which grants the resulting molecule distinct physical and chemical properties.
In my experience analyzing such compounds, it is clear that Tyr is the only major, natural nutrient containing an aromatic hydroxyl group, which significantly influences how these dipeptides interact with other chemical agents. Whether you are looking at the standard Phe-Ty Phe-Tyr | C18H20N2O4 r-OH or its isomer Tyr-Phe, the fundamental building blocks remain consistent. The Tyr-Phe variant, often cataloged under specific identifiers like 17355-11-2, is frequently utilized in proteomics research, where purity—often specified at ≥98%—is paramount for accurate data collection.
Specialized Derivatives and Research Applications
The versatility of these molecules extends to their derivatives. For example, Z-Phe-Tyr, which is a N-terminal blocked synthetic dipeptide, is recognized as a potent irreversible inhibitor of Tyr-Phe 17355-11-2 serine proteases. This specific functionality makes it a valuable tool in biochemical research and pharmaceutical applications, as it can effectively bind to the active site of enzymes to modulate their activity.
Other variations, such as Ac-Phe-Tyr-NH2 (Acetylphenyltyrosine amide), serve as synthetic peptides that mimic natural structures. These are critical for researchers investigating the complex interactions of dipeptides within synthetic systems. Furthermore, the study of Tyr-Phe dipeptide aggregation, including its micelle Catalog Number: AHY131. Synonym: H-Tyr(Me)-OH. CAS Number: [6230-11-1]. Molecular Weight: 195.2. Molecular Formula: C 1 0 H 1 3 NO 3. formation, provides deep insights into how these small chains organize themselves in solvents of varying polarity.
Comparative Perspective
When comparing different configurations, one might encounter sequences like H-Ser-Tyr-OH, which is another notable dipeptide. While structurally distinct from the Phe-Tyr arrangement, it shares the commonality of being a subject for structural and functional analysis. Even more complex chains, such as TYR-D-ALA-PHE-HYP-TYR-NH2 or the tripeptide Tyr-Phe-Tyr, demonstrate the expansive potential of peptide chemistry beyond simple two-residue chains.
From a structural standpoint, it is fascina Ser-Phe-Tyr | C21H25N3O6 | CID 145457853 - PubChem - NIH ting to observe how even subtle changes—such as the substitution of tyrosine with electron-d Ser-Phe-Tyr | C21H25N3O6 | CID 145457853 - PubChem - NIH eficient aromatic amino acids—can alter the stability and reactive profile of these compounds. The dipeptide Phe-Tyr có cấu trúc như hình (has a structure as shown in scientific literature) often serves as a baseline for these modifications, allowing researchers to study the impact of para-substituted phenol groups.
Observations on Stability and Utility
In my own practical engagement with these materials, I have noted that the stability provided by the aromatic linkage is a major advantage. Whether the goal is to observe the self-assembly of nanostructures or to study the cleavage processes enabled by novel hyperoxidation techniques, the Phe and Tyr residues provide a robust foundation.
It is important to note that these substance H-Phe-Tyr-OH (CAS 17355-18-9) s are intended strictly for research purposes. Their ability to serve as a synthetic peptide used in biochemical research and pharmaceutical applications underscores the necessity of maintaining high standards in handling and identification. Whether one is dealing with H-Phe-Tyr-OH or the broader class of Ser-Phe-Tyr compounds, the precision in molecular weight and purity ensures that the observed Tyr-Tyr - an overview | ScienceDirect Topics results remain consistent and verifiable within the scientific community.
