This compound, (S)-2,5-diaminopentanoic acid acetate (1:1), also known as L-ornithine acetate, is the acetic acid salt of L-ornithine, a non-proteinogenic amino acid crucial in the urea cycle for ammonia detoxification and nitrogen metabolism. It is primarily utilized in biochemical research and pharmaceutical development. In peptide and protein synthesis, it acts as a building block for creating specific amino acid sequences. It is also employed in studies of enzyme mechanisms and metabolic pathways, especially those related to the urea cycle and polyamine biosynthesis. In drug development, it can be incorporated into therapeutic agents targeting disorders of nitrogen metabolism, such as hyperammonemia or urea cycle defects. Furthermore, it is used in nutritional science for dietary supplements that support liver health, wound healing, athletic performance, and protein synthesis.
