Arginine is an amino acid compound that participates in the ornithine cycle in the human body, promotes the formation of urea, and converts the ammonia produced in the human body into non-toxic urea through the ornithine cycle. Arginine has three tightly bound nitrogen atoms in its side chain. It is an extremely alkaline amino acid with a pH of up to 12.5. Arginine metabolism ultimately produces a variety of biochemical products, including nitric oxide, urea, creatine, polyamines, proline, glutamate, agmatine, and homoarginine. The change of arginine concentration can also regulate cell metabolism and function through a variety of arginine sensors. Arginine forms an electrostatic complex with aspartic acid or glutamic acid to strengthen the tertiary structure of the protein. It also interacts with acidic groups attached to proteins, such as the phosphate groups of nucleic acids, thereby regulating the function of proteins, which are essential amino acids for maintaining growth and development. Arginine can be used in biochemical research. For example, as an intercellular messenger in the nitric oxide pathway, it plays an important role in the regulation of the nervous system. It is also used as a nutritional supplement, flavoring agent and food flavor in the food field.
