In the evolving field of biochemical research, the study of small molecular structures has become i Buy L-Tyrosine, N-glycyl- | 658-79-7 | >98% ncreasingly vital. As a frequent observer of peptide science, I have found that the Gly Tyr dipeptide—often referred to as Glycyl-L-tyrosine—offers a fascinating look into how simple amino acid linkages can influence complex biological systems.
Understanding the Structure of Gly Tyr Dipeptide
At its co Tyr-Gly | C11H14N2O4 re, Gly-Tyr is a dipeptide composed of two essential building blocks: glycine and tyrosine. The molecular formula for this compound is C11H14N2O4, with an average mass of 238.243 g/mol. From a structural perspective, Gly-Tyr is a dipeptide that bridges the simplicity of the smallest amino acid, Ile-Gly-Tyr - (CAS 205865-70-9) - Peptides Gly, with the aromatic complexity of Tyr.
When we look at the chemical notation, NH2CH2CONHCH(COOH)CH2C6H4OH represents the specific arrangement of these residues. Unlike free L-tyrosine, which is known for its relatively low aqueous solubility, Gly-Tyr (Glycyl-tyrosine, GY) exhibits signific Gly-His-Tyr | C17H21N5O5 | CID 145455634 - structure, chemical names, physical and chemical properties, classification, patents, literature, antly higher solubility in water. This property makes it a preferred candidate for researchers looking to stabilize biological environments without the precipitation issues often associated with lone tyrosine.
Distinguishing Between Related Peptides
It is common for those new to the field to confuse various chain lengths. It is important to distinguish between CN103172695A - Preparation method of glycyl-tyrosine the dipeptides and longer chains. For instance:
* Ile-Gly-Tyr is a tripeptide: Featuring an additional isoleucine residue, this structure is distinct from the simpler Gly-Tyr form.
* Ala-Gly-Tyr is a tripeptide: Another variation that incorporates alanine, showing how peptide linkages can be expanded.
* Gly-Ala-Tyr: A substrate often used to study enzymatic activity.
* Gly-His-Tyr: A unique sequence often explored for specific binding affinities.
* Tyr-Gly-Gly-Phe-Leu-Lys: A more complex synthetic peptide that functions differently than the basic dipeptide unit.

My experience with these compounds highlights their role in peptide synthesis and cell culture media. Glycyl-L-tyrosine is a synthetic dipeptide that serves as a consistent source of tyrosine in specialized environments. For example, Gly-L-Tyr can be easily supplemented to the main feed in cell culture models, ensuring that the necessary amino acid availability is maintained at a neutral pH.
Furthermore, Glycyl-L-tyrosine dihydrate is a white solid dipeptide that provides high purity (often >99%) for sensitive experimental setups. Whether you are dealing with Tyr-Gly or its isomer, the stability of these compounds is paramount. I typically store these materials at -20°C to maintain their integrity over long-term research cycles.
Contextualizing the Amino Acid Components
To appreciate the Gly Tyr dipeptide, one must understand its constituents. L-Tyrosine is an aromatic amino acid that is essential f Cyclo(Gly-Tyr) | Cyclic dipeptide | glycine and tyrosine or protein biosynthesis. Conversely, Gly is the smallest amino acid, offering structural flexibility. When combined, the resulting molecule is an organic compound known as a dipeptide.
While some may confuse these with endogenous substances like Dyn (an endogenous opioid heptadecapeptide), it is crucial to remember that Gly-Tyr is primarily a tool for structural biology and chemical research. Whether investigating the oxidation of glysyl tyrosine or exploring how Trp-Tyr is a dipeptide structure that influences specific cell signaling pathways, the study of these compounds remains a cornerstone of modern laboratory investigations.
Final Thoughts on Handling
When working with Gly-Tyr, always ensure you are using high-grade materials. The crystalline and amorphous phase differences can sometimes affect solubility, so verifying the CAS number (658-79-7 for the standard Gly-Tyr) is a standard best practice. While some researchers look into Gly tyr dipeptide supplement or Gly tyr dipeptide powder for external research applications, the primary value of these substances lies in their ability to provide controlled, reproducible results in non-clinical, academic, or industrial biochemical research settings.
