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 (Alanin Ala-Leu Peptide – Powder – 1 g – Biotechnology e-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 ile-ala. Unverified. 2-(2-amino-3-methylpentanamido)propanoic acid.

Ala (Alanine) is a non-essential amino acid known for its simplicity, while Ile (Isoleucine) is an essential branched-chain aliphatic amino acid found in many prot Jul 22, 2020 — We report here the striking water solubility of the Ala-Ile dipeptide (up to 0.05 g/cm3 in water) and compare its tendency to self-assemble in eins.
When 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 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-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 suitable for bio Ala-Leu is a dipeptide made of alanine (Ala) and leucine (Leu). Alanine is a non-polar amino acid found in proteins, while leucine is an essential branched chemical applications to ensure high purity in their experiments. Whether working with natural isomers or non-natural diastereomers like Fmoc-allo-Ile-O D-Alanyl-D-Alanine | C6H12N2O3 | CID 5460362 - PubChem H, 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.
In summary, the study of the dipeptide Ala Ile provides a window into the complex world of peptide interactions.
