Used in biochemical research as a modified amino acid for studying enzyme activity and protein structure. Its unique side chain allows it to act as a substrate analog in metabolic pathways, particularly in investigations involving arginine metabolism. The compound is also utilized in the development of enzyme inhibitors due to its ability to mimic natural amino acids while resisting rapid degradation. Its structural features make it valuable in designing peptidomimetic compounds for pharmaceutical applications, especially in targeting specific proteases and nitric oxide synthase pathways.
