Description

H-Ala-Ala-Ala-Tyr-Ala-Oh is a synthetic pentapeptide sequence featuring a tyrosine residue, which is a critical component in biochemical research and development. This compound matters as a high-purity building block for studying enzyme-substrate interactions, protein folding, and peptide-based drug discovery. It is primarily needed by research institutions, pharmaceutical R&D departments, and biotechnology companies focused on proteomics and therapeutic peptide synthesis.

Application

• Biochemical Research: Used as a model substrate for studying protease (e.g., chymotrypsin) activity, kinetics, and specificity due to the tyrosine cleavage site.
• Pharmaceutical Development: Serves as a key intermediate or reference standard in the synthesis and quality control of more complex therapeutic peptides.
• Proteomics & Enzymology: Employed in enzyme assay development and for calibrating analytical instruments like HPLC and mass spectrometers in protein analysis workflows.
• Academic Studies: Utilized in university laboratories for teaching advanced concepts in peptide chemistry, enzymology, and molecular biology.
• Antigen Synthesis: Can be used as a hapten or a component in synthesizing peptide antigens for antibody production and immunological studies.
