Products Usage
1.Arginine is the only substrate for the synthesis of NO, which is synthesized under the catalysis of NOS. NO is an important immunomodulatory factor.
The NO pathway of arginine plays an important role in regulating body immunity and protecting intestinal mucosa function. Arginine can also promote the production of immunoglobulin and effectively enhance humoral immunity. Studies have shown that supplementing arginine in the diet can enhance the immunity of pregnant sows and newborn piglets, thereby reducing the morbidity and mortality of piglets.
2.For endocrine, arginine can stimulate the body to secrete growth hormone and insulin, which play important roles in the metabolism of sugar and protein in body tissues.
3.The NO pathway of arginine is vital in maintaining the constant vascular tension and regulating the stability of blood pressure.
4.Anti-oxidative stress
L-arginine is the body’s free radical scavenger. NO is produced by the reaction of L-arginine and molecular oxygen catalyzed by NOS. It is a new type of cell information molecule that can expand blood vessels, inhibit platelet aggregation, inhibit cell proliferation, and inhibit Lipid peroxidation and formation of end-products of glycosylation, etc.
