In the realm of biochemical research and synthetic peptide chemistry, understanding the structural nuances of short-chain peptides is essential. Among these, the dipeptide Ala Ile (Alanine-Isoleucine) stands out as a fascinating subject for study. As someone who has long observed the development of peptide building blocks, I find the properties of this specific sequence, often cataloged under Molecular formula: C9H18N2O3, to be particularly compelling for those interested in molecular self-assembly and structural analysis.
Structural Insights and Properties
At its core, Ala-Ile—also referred to by its systematic name 2-(2-amino-3-methylpentanamido)propanoic acid—represents a fundamental pairing of two aliphatic amino acids. Ala (Alanine) is a non-essential amino acid known for its simplicity, whil (IUCr) Z-Ala–Ile-OH, a dipeptide building block suitable for the e Ile (Isoleucine) is an essential branched-chain aliphatic amino acid found in many proteins.
ALA Ligand Summary PageWhen these two amino acids (in this case leucine and alanine) combine together—or in this case, alanine and isoleucine—they form a peptide bond that dictates the molecule's physical behavior. One of the most remarkable findings in recent literature is the water solubility of the Ala-Ile dipeptide, which has been measured up to 0.05 g/cm³ in water. This solubility profile makes it a unique candidate for further investigation in aqueous environments.
The Role of Self-Assembly
One of the most exciting aspects of alanine-isoleucine (Ala-Ile) is its classification as a nanotube-forming dipeptide. Researchers have highlighted that self-assembling dipeptides have emerged in the last two decades Ala-Gly 687-69-4 as promising building blocks for the development of novel biomaterials.
In my own review of laboratory materials, I have noted that H-Ala-Ile-OH (CAS# 29727-65-9) is frequently sought after by those working on advanced structural models. Because it acts as a nonpolar dipeptide, it offers a distinct contrast to more hydrophilic sequences. It is often used as a model dipeptide in physicochemical studies, helping researchers understand how side-chain interactions influence the overall conformation of short peptides.
Comparative Analysis in Peptide Chemistry
In the broader context of peptide synthesis, Ala-Ile is often compared to other common sequences. For instance, Leu-Ala (or ala-leu) is another common motif, as is the Ala-Leu-Ile tripeptide. While D-Ala-Leu is a dipeptide formed from D-alanine and L-leucine residues, the L-form of Ala-Leu Peptide Ala-Ile remains a standard reference in structural biology.
For those involved in sophisticated synthesis, the availability of specialized reagents is crucial. Just as Fmoc-Ile-OH (1-13C) is utilized for precise isotope labeling, researchers often look for a biotechnology-grade powder suita Alanyl dipeptides such as ala-leu, ala-lys, ala-gly, ala-pro, ala-tyr and ala-phe may be used in physicochemical studies or to evaluate dipeptide separation ble for biochemical applications to ensure high purity in their experiments. Whether working with natural isomers or non-natural diastereomers like Fmoc-allo-Ile-OH, the precision of the starting material is paramount.
Broader Applications
Beyond simple structural studies, these compounds touch on fascinating areas of biochemistry:
* Non-proteinogenic amino acid research, which often involves studying variants like allo-isoleucine.
* Complex sequences such as Ala-His-Ile, which expand the functional diversity of peptide libraries.
* The study of D-Ala-Leu as a metabolic reference point in controlled environments.
