L-Arginine 99% | 74-79-3
Product Description:
Arginine, with chemical formula C6H14N4O2 and molecular weight of 174.20, is an amino acid compound. Participates in 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 ornithine cycle, which is excreted in urine, thereby reducing blood ammonia concentration.
There is a higher concentration of hydrogen ions, which helps to correct the acid-base balance in hepatic encephalopathy. Together with histidine and lysine, it is a basic amino acid.
The efficacy of L-Arginine 99%:
For biochemical research, all kinds of hepatic coma and abnormal hepatic alanine aminotransferase.
As nutritional supplements and flavoring agents. Special aroma substances can be obtained by heating reaction with sugar (amino-carbonyl reaction). GB 2760-2001 specifies the permitted food spices.
Arginine is an essential amino acid to maintain the growth and development of infants and young children. It is an intermediate metabolite of the ornithine cycle, which can promote the conversion of ammonia into urea, thereby reducing blood ammonia levels.
It is also the main component of sperm protein, which can promote sperm production and provide sperm movement energy. In addition, intravenous arginine can stimulate the pituitary to release growth hormone, which can be used for pituitary function tests.
