The article summarizes actual information about L-arginine (Arg), which is the semi-essential amino acid. L-arginine is classified as an essential amino acid for birds, carnivores and young mammals and a conditionally essential amino acid for adults. L-arginine plays very important role in the plant and animal body metabolism. It metabolically interconvertible with the amino acids proline and glutamate and also is the precursor of a large number of crucial metabolites. It is serves as a precursor for synthesis of molecules of great biological importance, including proteins, L-ornithine, polyamines, agmatine, creatine and urea, which is important in the urea cycle. The main importance of L-arginine is attributed to its role as a precursor for the synthesis of nitric oxide (NO), a free radical molecule that is synthesized in all mammalian cells from L-arginine by NO synthase. NO appears to be a major form of the endothelium-derived relaxing factor. So, L−arginine plays a special role in vascular system, where it is a source of endogenous nitric oxide, which is blood vessels dilator. The use of supplements with L-arginine is appropriate in the prevention and treatment of metabolic diseases. Thanks to relaxation of vascular smooth muscles, it takes part in regulation of blood vessels tone. Treatment by arginine as a medicine improves functions of cardiovascular system. L-Аrginine there is in plant and animal food and in seafood. L-arginine has a wide and varied application such as animal feeding, cosmetology, medical field. In recent years arginine production has been increasing. L−Arginine is obtained by hydrolysis of proteins, with the help of chemical and microbiological synthesis. Microbiological synthesis of L-arginine is the most promising and economically advantageous. Modern microbial technologies use monosubstrates and mixed substrates. Bacteria can synthesize all 20 proteinogenic amino acids, including the nine essential amino acids required for mammalian growth. In general, enzymes involved in the ...
