Source and Preparation

Obtained by separation of protein hydrolysates, such as gelatin, by ion exchange resins or barium hydroxide. It is usually made into hydrochloride, but it is also stable in the free state. It can also be obtained by fermentation with sugar as raw material.

Applications

For biochemical research, all kinds of liver coma and viral liver alanine transaminase abnormal. As a nutritional supplement and seasoning agent. Special flavor substances can be obtained by heating with sugars (amino - carbonyl reaction). Arginine is an essential amino acid to maintain the growth and development of infants. It is an intermediate metabolite in the ornithine cycle, which promotes the conversion of ammonia to urea, thereby reducing blood ammonia levels. It is also the main component of sperm protein, has the role of promoting spermatogenesis, provide spermatogenesis energy. In addition, intravenous injection of arginine can stimulate the pituitary to release growth hormone, which can be used for pituitary function test.
