Metabolic state of the rat liver with ethanol: Comparison of in vivo31phosphorus nuclear magnetic resonance spectroscopy with freeze clamp assessment
John H. Helzberg, Mark S. Brown, Daniel J. Smith, John C. Gore, Ellen R. Gordon – 1 January 1987 – In vivo31phosphorus nuclear magnetic resonance spectroscopy was used to measure the hepatic metabolic state in various groups of rats given ethanol, a control liquid diet or a solid chow diet. The use of selective presaturation pulses applied to the broad phosphorus resonances of immobile phospholipids permitted reliable determination of ATP/ADP ratios by quantitation of the ATP‐β and ATP‐γ peak areas.
