(gwahn'i-dēn, -din),
A strongly basic compound, usually found (in some plants and lower animals) as the hydrochloride; a constituent of creatine and arginine.

guanidine

/gua·ni·dine/ (gwah´nĭ-dēn) the compound NHdbondC(NH2)2, a strong base found in the urine as a result of protein metabolism and used in the laboratory as a protein denaturant. The hydrochloride salt is used in the treatment of myasthenia gravis.

guanidine

(gwä′nĭ-dēn′)
n.
A strongly alkaline crystalline compound, NHC(NH2)2, formed by the oxidation of guanine and found in the urine as a normal product of protein metabolism. It is commonly used in the organic synthesis of plastics, resins, and explosives.

guanidine

the amidine of amino carbamic acid. The hydrochloride preparation is used to increase acetylcholine release in the treatment of myasthenia gravis and botulism.
