The chemical substance "H-Ala-Ala-Ala-Tyr-OH," with the CAS number 112079-60-4, is a peptide composed of four amino acids: three alanine (Ala) residues and one tyrosine (Tyr) residue. This peptide is characterized by its sequence, which indicates that it has a free carboxyl group (-COOH) at one end, making it a C-terminally modified peptide. The presence of alanine, a non-polar, hydrophobic amino acid, contributes to the peptide's overall hydrophobic character, while the tyrosine residue introduces a polar aromatic side chain, which can participate in hydrogen bonding and contribute to potential interactions with other molecules. The peptide's structure and properties can influence its biological activity, stability, and solubility in various environments. Peptides like H-Ala-Ala-Ala-Tyr-OH are often studied for their roles in biological systems, potential therapeutic applications, and as models for understanding protein folding and interactions.
