Among these, the dipeptide asp lys (Aspartyl-Lysine) stands out as a subject of significant interest for those investigating biochemical pathways and molecular interactions. As someone deeply engaged in the study of peptide compounds, I have found that examining the structural integrity and chemical properties of such molecules provides a clearer picture of how amino acid residues interact at a foundational level.
Understanding the Chemical Identity of Asp-Lys
The dipeptide asp lys is uniquely defined as a dipeptide formed from L-lysine and L-aspartic acid residues. With a mol Showing Compound Aspartyl-Lysine (FDB111812) ecular formula of C10H19N3O5, this compound, often referred to as D-K dipeptide, represents a precise linkage between an acidic amino acid and a basic one.
From a structural perspective, the Asp (aspartic acid) component contributes a carboxylic acid side chain, while the Lys (lysine) component provid iRGD Peptide es an amino side chain. This creates a fascinating interplay of charges. Researchers often look at how this molecule maintains stability across a range of physiological pH levels, which is a critical observation for anyone evaluating the behavior of short-chain peptides in various experimental environments.
Key Characteristics and Structural Data
When analyzing Asp-lys, it is helpful to reference standardized data:
* Molecular Weight: 261.28 g/mol.
* CAS Number: 5891-51-0.
* Classification: Organic compound (dipeptide).
Unlike complex structures like the iRGD peptide (cyclic[Cys-Arg-Gly-Asp-Lys-Gly-Pro-Asp-Cys]) or the long-chain Asp-Tyr-Lys-Asp-Asp-Asp-Asp-Lys (frequently recognized as the Flag peptide sequence), the simplicity of the dipeptide asp and lys combination allows for easier observation of its intrinsic properties. It is a polypeptide that can be found by peptide screening, a technique used to identify active sequences within larger protein pool Lys-Asp is a dipeptide formed from L-lysine and L-aspartic acid residues. It has a role as a metabolite. It is functionally related to a L-aspartic acid and s.
Research Applications and Comparative Analysis
My personal experience with these compounds suggests that they are vital for understanding molecular bonding. For instance, comparing Asp-Lys to other variations—such as L-Lys-D-Asp (a dipeptide obtained by formal condensation) or even more complex trimers like Lys-Gly-Asp and Lys-His-Asp—highlights h AnaSpec offers two standard Heavy-Isotope Labeled Lysine amino acids: Fmoc-Lys(Boc)-OH (1-13C) and Fmoc-Lys(Boc)-OH (U-13C6, U-15N2). ow the sequence of amino acids dictates chemical behavior.
Furthermore, these structures may be used in studies of prebiotically relevant Salt-Induced Peptide Formation (SIPF). This research is instrumental for those exploring how simple molecules might have evolved into more complex biological frameworks. Whether one is looking at the solubility of lys (which is a soluble amino acid with a positive side chain) or the acidic nature of aspartic acid (Asp), the combination within a dipeptide provides a stable model for testing.
Observations on Stability and Sequence
In experimental settings, the stability of a dipeptide is paramount. While some sequences like those containing Gly-Asp-Asp-Asp-Asp-Lys-β-naphthylamide are used for specific enzymatic assays, the basic Asp-lys remains a gold standard for studying fundamental peptide synthesis. Its behavior is predictable, and its molecular architecture is well-documented in databases like PubChem and ChemSpider, providing a reliable reference point for any enthusiast or researcher.
