Purpose

For biochemical research, all kinds of liver coma and viral liver glutamic-pyruvic transaminase abnormity. Nutritional supplements; Flavoring agent. A heating reaction with sugar (aminocarbonyl reaction) can obtain a special flavor substance. GB 2760-2001 specifies the permissible use of spices for food. An important component of amino acid infusion and synthetic amino acid preparation. Arginine is an essential amino acid for infant growth and development. It is an intermediate metabolite in the ornithine cycle and can promote the conversion of ammonia to urea, thereby reducing blood ammonia levels. It is also the main component of spermatogenic protein, which promotes spermatogenesis and provides spermatogenic energy. In addition, intravenous injection of arginine can stimulate the pituitary to release growth hormone, which can be used for pituitary function test. Nutritional supplements; Flavoring agent.
