Description

L-Ornithine 2-Oxoglutarate is a stable, pharmaceutically relevant salt formed from the amino acid L-Ornithine and 2-Oxoglutaric acid (α-ketoglutarate). This compound is valued for its role in metabolic pathways, particularly in the urea cycle and amino acid synthesis. It is primarily utilized by manufacturers in the pharmaceutical and nutraceutical industries for the formulation of clinical nutrition products and dietary supplements.

Application

• Pharmaceutical Intermediates: Serves as a key active pharmaceutical ingredient (API) or precursor in metabolic and hepatoprotective drugs.
• Clinical Nutrition: Formulated into parenteral and enteral nutrition solutions for patients with specific metabolic needs or liver conditions.
• Dietary Supplements: Used in sports nutrition and wellness supplements targeting ammonia detoxification, muscle recovery, and energy metabolism.
• Biochemical Research: Employed as a standard or reagent in metabolic studies, enzymology, and cellular research.
• Veterinary Medicine: Incorporated into feed additives or therapeutic formulations for livestock and companion animals.
