L-arginine is one of the 20 amino acids that make up protein. It is a non-essential amino acid that can be synthesized in the body. L-arginine is the precursor of nitric oxide and other metabolites. It is an important part of collagen, enzymes and hormones, skin and connective tissue. L-arginine plays an important role in the synthesis of various protein molecules. L-arginine hcl is an important part of amino acid liquid and comprehensive amino acid preparations. Arginine α-ketoglutarate (AAKG) is a product composed of arginine and α-ketoglutarate, both of which can be used as raw materials for dietary supplements.

1.L-Arginine can be used as nutritional supplement; flavoring agent. For adult non essential amino acids, but the body produce slower,as the essential amino acids for infants and young children,certain detoxification. Heated reaction with sugar available special flavor. Infusion of amino acids and amino acids essential component of preparation.

2.L-Arginine is an amino acid base pairs, for adults, although not essential amino acids, but in some cases,such as immature or organism under conditions of severe stress, the absence of arginine, the body can not maintain positive nitrogen balance and normal physiological function. Lack of arginine may lead to the patient if the ammonia is too high,and even coma. If infants with congenital lack of certain enzymes of the urea cycle,arginine it is necessary, or can not maintain its normal growth and development.

3.L-Arginine important metabolic function is to promote wound healing,it can promote the synthesis of collagen, it can repair the wound. Secretion of fluid in the wound can be observed the increase of arginase activity, which also shows that the wound in the vicinity of the arginine requirement substantially. Arginine can promote micro circulation around the wound and promote wound healing as soon as possible.
