Description
Arginine is an amino acid compound. Participate in the ornithine cycle in the human body, promote the formation of urea, and convert the ammonia produced in the human body into non-toxic urea through the ornithine cycle, which is excreted in the urine, thereby reducing the blood ammonia concentration. There is a higher concentration of hydrogen ions, which helps to correct the acid-base balance in hepatic encephalopathy.
Arginine is obtained by separating protein (such as gelatin) hydrolyzate by ion exchange resin or barium hydroxide. Usually made into hydrochloride, it is also stable in a free state, so there are also free products for sale. It can also be obtained by fermentation with sugars as raw materials.
