A Study on the Formation Reactions and Conversion Mechanisms of HONO and HNO₃ in the Atmosphere of Daejeon, Korea

Atmosphere
Nitrogen oxides (NOX) in the atmosphere cause oxidation reactions with photochemical radicals and volatile organic compounds, leading to the accumulation of ozone (O3). NOX constitutes a significant portion of the NOy composition, with nitrous acid (HONO)

Nitrogen isotope analysis of ammonium and glycine [PDF]

, 2005
Stable isotope techniques can be used as a tool in nitrogen cycling studies of different ecosystems. The studies are based on measurement of the heavy (15N)- to- light (14N) isotopic ratios of nitrogen in different biospheric pools.

The conversion of L-histidine to glutamic acid by liver enzymes [PDF]

, 1952
Edlbacher and Neber (1) showed in 1934 that the liver enzyme named histidase degrades histidine to NH3, formic acid, and an unknown product which on further treatment with strong alkali yields glutamic acid.
