L-瓜氨酸    L- Citrulline

CAS No.372-75-8

Molecular formulaC6H13N3O3

Molecular weight175.19

Property: white crystal or crystalline powder, it tastes sour, soluble in water, insoluble in ethanol and ether.

Citrulline, is a kind of alpha amino acid, it was named from the first extraction from watermelon. Citrulline is formed from ornithine in the urea cycle, or the side products of arginine through a nitric oxide synthase (NOS) catalyzation. Citrulline can relax people’s vascular and be used to enhance male sexual function as well as treat sexual dysfunction. It can maintain health pulmonary function, improve mental clarity, help nerve cells in the brain to store and back the message.

Application:

Improve the immune system, maintain joint motion function, balance normal blood glucose levels. It is rich in antioxidants to absorb harmful free radicals. It helps to maintain normal cholesterol levels and healthy pulmonary function. It can improve mental clarity, decrease pressure and overcome depression emotion.
