Used in biochemical and pharmaceutical research as a peptide-based compound for studying enzyme activity, particularly with proteases and peptidases. Commonly employed in the development of enzyme assays due to its chromogenic and fluorogenic properties when modified. Serves as a model substrate for investigating receptor-ligand interactions in neurochemical studies. Also utilized in the synthesis of larger peptide sequences for structure-activity relationship (SAR) analysis. Its stability and specific side-chain functional groups make it valuable in drug design and screening platforms targeting neurological and metabolic disorders.
