When deuterium oxide, an isotopic form of water known as "heavy water," is drunk, it allows researchers to monitor carbon dioxide production, which in turn provides a very accurate measure of calories burned.
Identification of 3,4-Dihydroxy-2-oxo-butanal (L-threosone) as intermediate compound in oxidative degradation of dehydro-L-ascorbic acid and 2,3-diketo-L-gulonic acid in a deuterium oxide phosphate buffer.
The measurement of deuterium oxide in body fluids by the falling drop method.
In their experiments, Pons and Fleischmann pass an electrical current between palladium and platinum electrodes immersed in a flask containing lithium ions dissolved in deuterium oxide -- a heavy version of water made of oxygen and the hydrogen isotope deuterium.
1]H-NMR analysis, we added 20 [micro]L of deuterium oxide, containing 3-(trimethylsilyl)-2,2',3,3'-tetradeuteropropionic acid (TMSP-[d.
Deuterium oxide is thus two atomic mass units heavier than hydrogen oxide.
Moreover, where deuterium oxide dilution requires drawing blood and underwater weighing requires immersion in a calibrated pool, the infrared technique can be completed in three minutes and may ultimately require no more than the rolling up of one's sleeve.
