arginine

 (Arg) (R) [ahr´jĭ-nēn]
a nonessential amino acid that occurs in proteins and is involved in the urea cycle and in the synthesis of creatine. Preparations of the base or the glutamate or hydrochloride salt are used in the treatment of hyperammonemia and in the assessment of pituitary function.

An amino acid, C6H14N4O2, obtained from the hydrolysis or digestion of plant and animal protein.

arginine

Biochemistry
A facultatively essential amino acid that contains a guanido group with a pKa > 12, which carries a positive charge at physiological pH; it becomes an essential amino acid when the body is under stress or injured.

Sources
Food—turkey, chicken and other meats.
 
Fringe medicine
An amino acid believed to decrease cancer risk, and given as a nutritional supplement; arginine stimulates sperm motility.
