Arginine, which is also known as L-arginine, is an essential amino acid for humans. Arginine is present in all protein-containing foods such as grains, beans, nuts, meat, dairy products, and eggs, and it is also synthesized in the body from glutamine via citrulline amino acid. Arginine plays an important role in cell division, wound healing, removal of ammonia from the body, boosting immune function, and in the release of hormones. 更多
