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.
On 24 April 1880 Ostwald married Helene von Reyher (1854â1946), with whom he had five children: 1  Grete (born 1882 in Riga; died 1960 in GroÃbothen) 2  Wolfgang (born 1883 in Riga; died 1943 in Dresden) 3  Elisabeth (born 1884 in Riga; died 1968 in GroÃbothen) 4  Walter (born 1886 in Riga; died 1958 in Freiburg im Breisgau)
