Abstract

Phosphorus signifies an essential element in molecular biology, yet given the limited solubility of phosphates on early Earth, alternative sources like meteoritic phosphides have been proposed to incorporate phosphorus into biomolecules under prebiotic terrestrial conditions. Here, we report on a previously overlooked source of prebiotic phosphorus from interstellar phosphine (PH 3) that produces key phosphorus oxoacids—phosphoric acid (H 3 PO 4), phosphonic acid (H 3 PO 3), and pyrophosphoric acid (H 4 P 2 O 7)—in interstellar analog ices exposed to ionizing radiation at temperatures as low as 5 K. Since the processed material of molecular clouds eventually enters circumstellar disks and is partially incorporated into planetesimals like proto Earth, an understanding of the facile synthesis of oxoacids is essential to untangle the origin of water-soluble prebiotic phosphorus compounds and how they might have been incorporated into organisms not only on Earth, but potentially in our universe as well.

  • Compounds crucial for life such as phosphorous oxoacids are omnipresent in the universe.

    “Compounds crucial for life such as phosphorous oxoacids are also omnipresent in the universe due to their formation in interstellar clouds and dust particles from phosphine and water, and their transport through disks and planetesimals to planets and moons (Turner et al. 2018).”

    From The Emergence of Life (2019) · cites this paper as Turner et al. 2018

    The Introduction describes the synthesis of biologically relevant phosphorus oxoacids in interstellar-ice analogs, and the Abstract says molecular-cloud material can enter circumstellar disks and planetesimals. But the paper presents incorporation into planetary material as a possibility, not evidence that these oxoacids are omnipresent throughout the universe; it also does not establish delivery to moons.

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.
