Descrição geral

Deuterium oxide (D2O) is also known as heavy water. It is the deuterated form of water, as both the protons in H2O have been replaced with a deuterium isotope.

Aplicação

D2O can be used as a solvent in:      
  • High-resolution NMR (Nuclear magnetic resonance)      
  • FTIR (Fourier-transform infrared)      
  • Bio NMR studies      
  • Polarized visible Raman spectroscopic studies      
  • Protein expression

D2O is also used to prepare deuterium-labeled compounds in various fields such as pharmaceutical, bioanalytical, biological, and environmental chemistry via H-D exchange reactions to study drug metabolism mechanisms, reaction mechanisms, and the structure of biomolecules, and residual agrochemicals in foods using suitable analytical methods.

Hyperventilation is known to decrease cerebral blood flow (CBF) and to impair cerebral metabolism, but the threshold in patients undergoing intravenous anesthesia is unknown. The authors hypothesized that reduced CBF associated with moderate hyperventilation might impair cerebral aerobic metabolism in

Traditional proteomics provides static assessment of protein content, but not synthetic rates. Recently, proteome dynamics with heavy water ((2)H2O) was introduced, where (2)H labels amino acids that are incorporated into proteins, and the synthesis rate of individual proteins is calculated
