Arginine. Arginine, or L-arginine as it is called with its L-structure, is a semi-essential amino acid. Arginine is involved in many metabolic processes and important in the treatment of heart diseases and high blood pressure.
Layman's explanation: Nitric acid was first discovered in 1648 by a German chemist, Johann Rudolf. However, in 1901 Wilhelm Ostwald developed the Ostwald Process, which became the principle way of producing nitric acid.
Ostwald Process - oxidation of ammonia As you have studied, reacting nitrogen and oxygen is not an economic way of making nitric acid. The chemist Ostwald discovered a way to react oxygen and ammonia - the first step in nitric acid manufacture. The most important stage of this manufacture is the catalytic oxidation of ammonia Ammonia + oxygenânitrogen monoxide + water
