Nalpha-benzoyl-L-arginine is widely used in biochemical research as a substrate for studying enzyme activity, particularly for proteases like trypsin. It helps in understanding enzyme kinetics and mechanisms due to its specific interaction with these enzymes. Additionally, it serves as a key intermediate in the synthesis of peptides and other bioactive compounds. In pharmaceutical studies, it aids in the development of enzyme inhibitors and therapeutic agents targeting protease-related diseases. Its role in research extends to investigating blood clotting processes and other physiological functions involving arginine derivatives.
