The chemical substance known as H-Ala-Ala-Pro-Ala-OH, with the CAS number 53620-20-5, is a peptide composed of four amino acids: alanine (Ala) and proline (Pro). This peptide features a sequence that includes two alanine residues flanking a proline residue, with a carboxylic acid group (-COOH) at one end, indicating it is in its free acid form. Peptides like H-Ala-Ala-Pro-Ala-OH are typically characterized by their ability to participate in various biochemical processes, including protein synthesis and enzyme activity modulation. The presence of proline in the sequence can impart unique structural properties, such as rigidity and the ability to form turns in peptide chains. This compound may also exhibit biological activity, potentially influencing cellular functions or serving as a building block for larger peptides or proteins. Its solubility, stability, and reactivity can vary based on environmental conditions such as pH and temperature, making it relevant in both research and therapeutic contexts.

<p>H-Ala-Ala-Pro-Ala-OH is a tetrapeptide that inhibits elastase, an enzyme that breaks down elastin. This compound has been shown to have anti-elastolytic activity in vitro and in vivo. H-Ala-Ala-Pro-Ala-OH was administered intraperitoneally to hamsters with induced emphysema, resulting in a decrease of elastin abnormalities and improvement of the ultrastructure of the lungs. It also improves pancreatic morphology and function in porcine pancreatitis models.</p>
