Use	Arginine is an essential amino acid for the growth and development of infants and young children. It is an intermediate metabolite of the ornithine cycle that promotes the conversion of ammonia to urea, thereby reducing blood ammonia levels. It is also the main component of sperm protein, which promotes sperm production and provides energy for sperm movement. In addition, intravenous arginine, can stimulate the pituitary growth hormone release, can be used for pituitary function test.
