Molecular Paleohydrology: Interpreting the Hydrogen-Isotopic Composition of Lipid Biomarkers from Photosynthesizing Organisms
Dirk Sachse,Isabelle Billault,Gabriel J. Bowen,Yoshito Chikaraishi,Todd E. Dawson,Sarah J. Feakins,Katherine H. Freeman,Clayton R. Magill,Francesca A. McInerney,Marcel T J van der Meer,Pratigya J. Polissar,Richard J. Robins,Julian P. Sachs,Hanns Ludwig Schmidt,Alex L. Sessions,James W. C. White,Jason B. West,Ansgar Kahmen +17 more
TL;DR: In this paper, the authors review the factors and processes that are known to influence the hydrogen-isotopic compositions of lipids from photosynthesizing organisms, and provide a framework for interpreting their D/H ratios from ancient sediments and identify future research opportunities.

TL;DR: The factors and processes that are known to influence the hydrogen-isotopic compositions of lipids-especially n-alkanes-from photosynthesizing organisms are reviewed, and a framework for interpreting their D/H ratios from ancient sediments is provided to identify future research opportunities.

TL;DR: It is shown that two readily measured parameters, delta 15N measured on choline and delta18 O measured on total oil, can be successfully used to discriminate between fish of authentic wild and farmed origin and the certainty of identification of mislabeling in market-derived fish is strengthened by including the percentage of linoleic acid C18:2n-6 in the lipidic fraction.

Measurement of 2H distribution in natural products by quantitative 2H NMR: An approach to understanding metabolism and enzyme mechanism?
Richard J. Robins,Isabelle Billault,Jia-Rong Duan,Sébastien Guiet,Sébastien Pionnier,Ben-Li Zhang +5 more
TL;DR: In this article, the authors used 2H NMR spectroscopy to obtain mechanistic and regulatory information about isotopic fractionation from glucose during fermentation, and found that the (2H/1H) ratio shows an alternating pattern along the length of the chain and that the residual hydrogen atoms at the sites of desaturation are asymmetrically impoverished.
