Alkali Scientific L Ornithine HCl (L 2 5 Diaminopentanoic Acid), 1 Kilogram
L-Ornithine HCl is a key amino acid used in metabolic studies, particularly in the context of urea cycle research and nitric oxide synthesis. Available in a 1-kilogram bottle, it plays a critical role in the biosynthesis of arginine, which is essential for protein synthesis, cell division, and the production of polyamines. L-Ornithine is used as a supplement in cell culture media to promote cell growth and is often employed in animal studies related to liver function, muscle metabolism, and wound healing. It is also used in the synthesis of compounds involved in the regulation of cell growth and differentiation.
