Thus, knowing the isotopic fractionation of the common atoms, such as H, C, N, O or S, at each step during a metabolic pathway allows the construction of a unique isotope profile that reflects its past history. Having access to the isotope abundance gives valuable clues about the (bio)...
NMR-based isotopic and isotopomic analysis 2020, Progress in Nuclear Magnetic Resonance Spectroscopy Citation Excerpt : This last drawback can be overcome by specific methods. We have shown that accurate 1H quantitative NMR can be performed on concentrated samples by suppressing most of the signal ...
Isotopic analysisirm-NMRQuantitative NMRHigh accuracyPSIAMolecules exist in different isotopic compositions and most of the processes, physical or chemical, in liv-ing systems cause selection between heavy and light isotopes. Thus, knowing the isotopic fractionation of the common atoms, such as H, C...
