Overview
L-Ornithine is a non-proteinogenic amino acid that plays a critical role in the urea cycle, facilitating the detoxification of ammonia in the body. Unlike standard amino acids, it is not incorporated into proteins but is vital for metabolic processes. It is naturally produced in the body and can also be obtained through dietary sources or supplements. In industrial and pharmaceutical contexts, L-Ornithine is synthesized for use in medications, health supplements, and research applications. Its importance in ammonia metabolism makes it a key component in treatments for liver disorders and other conditions related to nitrogen excretion.
Physical and Chemical Properties
L-Ornithine is a white crystalline powder with a molecular weight of 132.16 g/mol. It is highly soluble in water, which makes it suitable for aqueous formulations in pharmaceuticals and supplements. The compound decomposes at around 140°C, so it requires careful handling during high-temperature processes. Its chemical structure includes both amino and carboxyl groups, typical of amino acids, but its side chain features an additional amino group. This unique structure allows it to participate in the urea cycle, where it helps convert toxic ammonia into urea for safe excretion by the kidneys.
Main Applications
L-Ornithine is primarily used in the pharmaceutical industry to formulate drugs that support liver function and treat hyperammonemia. It is also a popular ingredient in dietary supplements aimed at enhancing athletic performance and recovery, as it may help reduce fatigue and improve energy metabolism. In biochemical research, L-Ornithine serves as a precursor for the synthesis of other compounds, such as polyamines and proline. Its role in cell proliferation and tissue repair makes it valuable in studies related to wound healing and regenerative medicine.
Safety and Storage
L-Ornithine is generally regarded as safe when handled according to standard laboratory practices. It is non-toxic but should be stored in a cool, dry environment to prevent degradation. Exposure to moisture or extreme temperatures can compromise its stability and efficacy. For bulk storage, use airtight containers made of materials resistant to chemical interaction, such as high-density polyethylene. Labeling should clearly indicate the contents and include hazard information, though L-Ornithine is not classified as a hazardous substance under most regulatory frameworks.
B2B Procurement Guide
When procuring L-Ornithine in bulk, prioritize suppliers with certifications such as ISO, GMP, or USP to ensure product quality and consistency. Request certificates of analysis (CoA) to verify purity, which should typically be ≥98% for pharmaceutical-grade material. Consider the supplier’s ability to provide custom packaging and labeling to meet your specific requirements. Pricing can vary significantly based on order volume, purity, and supplier location, so obtaining multiple quotes is advisable. Establish long-term contracts with reliable suppliers to secure stable pricing and availability.
