Abstract

Natural-abundance isotopic substitution in isotopically prochiral groups of otherwise achiral molecules can provide stochastically formed enantiomeric excesses which exceed the sensitivity threshold of sensitive asymmetric autocatalytic (Soai-type) reactions. This kind of induction of chirality should be taken into consideration in in vitro model experiments and offer a new kind of entry into primary prebiotic or early biotic enantioselection in the earliest stages of molecular evolution.

  • The carbon, nitrogen, and oxygen isotope chirality of many organic compounds on Earth can be discriminated by asymmetric autocatalysis with amplification of the extremely small chiral influence between 13C/12C, 15N/14N, and 18O/16O.

    “The neglected carbon, nitrogen, and oxygen isotope chirality of many organic compounds on Earth can therefore be discriminated by asymmetric autocatalysis with amplification of the extremely small chiral influence between 13C/12C, 15N/14N and 18O/16O.108,109)”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
