Abstract

A minimal cell can be thought of as comprising informational, compartment-forming and metabolic subsystems. To imagine the abiotic assembly of such an overall system, however, places great demands on hypothetical prebiotic chemistry. The perceived differences and incompatibilities between these subsystems have led to the widely held assumption that one or other subsystem must have preceded the others. Here we experimentally investigate the validity of this assumption by examining the assembly of various biomolecular building blocks from prebiotically plausible intermediates and one-carbon feedstock molecules. We show that precursors of ribonucleotides, amino acids and lipids can all be derived by the reductive homologation of hydrogen cyanide and some of its derivatives, and thus that all the cellular subsystems could have arisen simultaneously through common chemistry. The key reaction steps are driven by ultraviolet light, use hydrogen sulfide as the reductant and can be accelerated by Cu(I)-Cu(II) photoredox cycling.

  • The cyanosulfidic scenario relies on formaldehyde and HCN to produce glyconitrile, plus schreibersite, hydrosulfide, copper and UV light to promote homologation to higher cyanohydrins.

    “This scenario relies on two main monomers, formaldehyde and HCN, to produce glyconitrile, plus the action of schreibersite ((Fe, Ni) 3P), hydrosulfide (HS−) as reducing agent, copper and ultraviolet light, to promote the homologation to higher cyanohydrins”

    From The protometabolic nature of prebiotic chemistry (2023) · cites this paper as [20]

    In Results and discussion, ‘Towards a geochemical scenario’ (page unavailable), the paper identifies hydrosulfide as a reductant and describes copper-assisted photoreduction; it also describes cyanide as a feedstock for homologation. But it presents schreibersite as a proposed source of phosphate, not an agent promoting homologation. Our copy does not describe formaldehyde and HCN producing glyconitrile as the two-monomer basis of this scenario. (LLM, conf=0.87)

  • Recent experiments from Sutherland's group lead to synthesis of activated nucleotides and a range of amino acids with moderately high yields from plausible prebiotic precursors in a plausible prebiotic environment.

    “the recent experiments from Sutherland’s group lead to a description of the synthesis of activated nucleotides and a range of amino acids with moderately high yields from plausible prebiotic precursors in a plausible prebiotic environment”

    From Natural pH Gradients in Hydrothermal Alkali Vents Were Unlikely to Have Played a Role in the Origin of Life (2016) · cites this paper as Patel et al. 2015

    The Abstract describes an efficient synthesis of activated pyrimidine ribonucleotides, and Results and discussion says the network’s individual steps have good to excellent yields. But the paper reports synthesizing α-aminonitrile precursors of a range of amino acids, not the amino acids themselves. It also outlines a plausible geochemical scenario rather than showing that the full network operated in one environment. (LLM, conf=0.87)

  • Under plausible prebiotic conditions, nitrogenous (nucleobases) and oxygenous (sugars) chemistries could simultaneously develop.

    “John Sutherland and co-workers (Patel et al., 2015) reported lately that under plausible prebiotic conditions, nitrogenous (nucleobases) and oxygenous (sugars) chemistries could simultaneously develop.”

    From The Origin and Early Evolution of Life: Homochirality Emergence in Prebiotic Environments (2023) · cites this paper as Patel et al., 2015

    The paper describes prebiotically plausible routes to sugars and pyrimidine ribonucleotides within a common reaction network. Its Conclusions say the products could arise in separate streams and pools over time, not that nucleobases and sugars were independently produced simultaneously; the claim overstates that specificity. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • Sutherland and co-workers obtained a prebiotic mixture containing two pyrimidine ribonucleotides, the aminonitrile precursors of 12 amino acids, glycerolphosphate, and remarkably almost nothing else.

    “They were able to obtain a prebiotic mixture containing two pyrimidine ribonucleotides, the aminonitrile precursors of 12 amino acids, glycerolphosphate (GP, a precursor of phospholipids), and remarkably almost nothing else.”

    From The Origin and Early Evolution of Life: Homochirality Emergence in Prebiotic Environments (2023) · cites this paper as Patel et al., 2015

    The Abstract and Results and discussion describe two pyrimidine ribonucleotides, glycerol phosphate, and routes to aminonitrile precursors of twelve amino acids. But the Comparison with other ‘prebiotic’ syntheses section says the whole network would be difficult to run in one pot, and the Conclusions envision products from separate streams eventually mixing in pools. The paper does not report obtaining the specified mixture with ‘almost nothing else.’ Page numbers are unavailable in our copy. (LLM, conf=0.90)

  • Several important classes of biomolecules, such as plausible prebiotic amino acids precursors, 2',3'-cyclic pyrimidine nucleotides, and glycerol phosphate, may have hydrogen cyanide and formaldehyde as common chemical precursors in the cyanosulfidic pathway.

    “They have shown that several important classes of biomolecules, such as plausible prebiotic amino acids precursors (Piotto et al., 2019), 2',3'-cyclic pyrimidine nucleotides, and glycerol phosphate, may have hydrogen cyanide ( 1 ) and formaldehyde as common chemical precursors in the aforementioned 'cyanosulfidic' pathway.”

    From The Origin and Early Evolution of Life: Homochirality Emergence in Prebiotic Environments (2023) · cites this paper as Patel et al., 2015

    The Abstract and Results and discussion describe routes from hydrogen cyanide to amino-acid precursors, 2′,3′-cyclic pyrimidine nucleotides, and glycerol phosphate. But the Conclusions identify hydrogen cyanide as the carbon and nitrogen source for the cyanosulfidic network; the Comparison with other ‘prebiotic’ syntheses mentions formaldehyde only as a feedstock for the separate formose reaction. The paper does not support formaldehyde as a common precursor in its cyanosulfidic pathway. (LLM, conf=0.89)

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.
