This dipeptide, consisting of tryptophan and alanine, is primarily used in biochemical research to study peptide interactions, enzyme mechanisms, and protein folding. It serves as a model compound for understanding the structural and functional properties of larger peptides and proteins. Additionally, it can be utilized in the development of peptide-based drugs, particularly in designing molecules with specific biological activities. Its role in synthetic peptide chemistry also makes it valuable for creating more complex peptide structures for therapeutic or diagnostic purposes.
