Structural Composition and Chemical Identity
The aspartyl alanine dipeptide—which belongs to the class of organic compounds known as dipeptides—is defined by its precise molecula Dipeptide - an overview | ScienceDirect Topics r architecture. With a molecular formula: C7H12N2O5, this compound is a quintessential example of a dipeptide composed of the amino acids aspartic acid and alanine.
When I look at the structure, I see the aspartyl residue linked to the alanine residue. This specific sequence is critical, especially when co α-Asp-ala | C7H12N2O5 nsidering the distinction between alpha and beta isomers. Research indicates that the crystal and molecular structures of these isomers have been studied extensively to understand their orientation at the atomic level. It is fascinating to note that Asp-Ala is a dipeptide that appears in various databases, often cataloged under specific IDs like CID 4677380, highlighting its role as a subject of rigorous chemical cataloging.
Functional Roles and Biological Significance
Beyond its structural profile, this molecule is more than just a static chemical entity. In certain contexts, the alpha-L-aspartyl-L-alanine isomer is a neurotransmitter, that plays a physiologic role in synaptic transmission. This specific functional characteristic makes it a subject of high interest for those studying the complexities of biological signaling.
Furthermore, the study of these compounds often involves enzymatic interactions. For instance, the beta-aspartylalanine variant is a substrate for β-aspartyl peptidase, an enzyme used to measure peptidase activity in various research models.

Comparative Analysis of Dipeptides
As I have navigated my own research, I have found it helpful to compare Aspartate Alanine dipeptide to other similar structures. For example:
* Aspartyl-serine is a dipeptide composed of aspartic acid and serine, which often appears as a breakdown product in protein catabolism.
* Asp-Val is a dipeptide formed from L-alpha-aspartyl and L-valine residues, which, like Asp-Ala, has been identified as a metabolite.
* Other derivatives, such as aspartylmethionine (Asp-Met) and aspartylcysteine, further demonstrate the versatility of the aspartyl group when paired with different amino acids.
Experimental Insights
When working with these molecules, researchers are often asked to perform tasks such as drawing the tetrapeptide Ala-Thr-Asp-Asn to practice identifying the peptide bonds that hold these chains together. My experience suggests that mastering the basics—such as understanding how Ala-Asn is a dipeptide composed of L-alanine and L-asparagine units—is key to grasping how larger, more complex structures like Ala-Asp-Gly (a tripeptide) or Ala-Asp-Pro function.
While some related compounds, such as L-aspartyl-L-phenylalanine, are known as a dipeptide inhibitor of angiotensin-converting enzyme (ACE), the primary focus for those of us looking at Asp-Ala remains its basic biochemical behavior. Whether you are analyzing Ala-Asp-His, Asp-Ala-Arg, or the more complex Asp-Ala-Phe, the rigorous study of these sequences provides a window into the building blo Asp-Ala; 5694-27-9; 3-AMINO-3-[(1-CARBOXYETHYL)CARBAMOYL]PROPANOIC ACID; Aspartate Alanine dipeptide; 3-amino-4-(1-carboxyethylamino)-4-oxobutanoic acid. cks of life.
