H-Tyr-Ala-OH（Cat No.:I044753）is a dipeptide composed of tyrosine (Tyr) and alanine (Ala) with a free N-terminal amine and C-terminal carboxylic acid group. This simple peptide sequence is often used in biochemical and pharmacological research to study peptide transport, enzymatic hydrolysis, and receptor interactions. The phenolic side chain of tyrosine imparts aromatic character and potential for hydrogen bonding, while alanine contributes structural simplicity and stability. H-Tyr-Ala-OH serves as a model compound in protease assays, peptide synthesis development, and structure–activity relationship studies in peptide-based drug discovery.
