Applications
L-Arginine is an encoding amino acid in protein synthesis and is one of the 8 essential amino acids in the human body. The body needs it for many different functions. Taking L-Arginine supplements can treat certain diseases such as congestive heart failure and cystitis. L-Arginine can also act as seasoning for nutrient supplements and food additives. L-Arginine can undergo a heat reaction with sugar (amino-carbonyl reaction) to obtain a unique fragrance, GB 2760-2001, an approved food spice. As an amino acid drug, L-Arginine can be used as pharmaceutical raw material and is an important ingredient in amino acid infusions and integrated amino acid preparations. It is also a crucial amino acid in maintaining infant growth and maturation.
L-Arginine can stimulate the human body to release certain chemicals such as insulin and human growth hormone. It can also clear ammonia in the body and promote the healing of wounds. The human body also needs it to produce sarcosine. Decomposing L-Arginine produces nitric oxide, which can expand blood vessels and increase blood flow. L-Arginine is an intermediate metabolite in the orthinine cycle and promotes the conversion of ammonia to urea, thus lowering the blood concentration of ammonia. L-Arginine is also an important part of sperm protein and can promote spermatogenesis and provide energy for sperm movement. Additionally, intravenous arginine can stimulate the pituitary to release growth hormone and can be used to test pituitary functions.
