The Lipid World

Open access

Abstract

The continuity of abiotically formed bilayer membranes with similar structures in contemporary cellular life, and the requirement for microenvironments in which large and small molecules could be compartmentalized, support the idea that amphiphilic boundary structures contributed to the emergence of life. As an extension of this notion, we propose here a 'Lipid World' scenario as an early evolutionary step in the emergence of cellular life on Earth. This concept combines the potential chemical activities of lipids and other amphiphiles, with their capacity to undergo spontaneous self-organization into supramolecular structures such as micelles and bilayers. In particular, the documented chemical rate enhancements within lipid assemblies suggest that energy-dependent synthetic reactions could lead to the growth and increased abundance of certain amphiphilic assemblies. We further propose that selective processes might act on such assemblies, as suggested by our computer simulations of mutual catalysis among amphiphiles. As demonstrated also by other researchers, such mutual catalysis within random molecular assemblies could have led to a primordial homeostatic system displaying rudimentary life-like properties. Taken together, these concepts provide a theoretical framework, and suggest experimental tests for a Lipid World model for the origin of life.

  • When published mutually catalytic values of lipids from Fendler were analysed, a similar distribution was observed.

    “Not less important, when published mutually catalytic values of lipids from Fendler [82] were analysed, a similar distribution was observed [55].”

    From Systems protobiology: origin of life in lipid catalytic networks (2018) · cites this paper as [55]

    Section 8 (p. 16) says the authors plotted Fendler’s lipid-related catalytic enhancement factors and found a distribution resembling the one used for their model. But Figure 6b (p. 14) identifies Fendler’s values as rate ratios for different reactions, mostly hydrolytic, in micelles—not measured mutual catalytic values between lipids. (LLM, conf=0.86)

  • Heterogeneous micelles bear similarity to globular proteins, being of similar size, having hydrophobic interior and hydrophilic functional surface with catalytic capacities.

    “In a related vein, heterogeneous micelles bear similarity to globular proteins, being of similar size, having hydrophobic interior and hydrophilic functional surface [55] with catalytic capacities (see next section).”

    From Systems protobiology: origin of life in lipid catalytic networks (2018) · cites this paper as [55]

    Section 6 (p. 11) explicitly describes heterogeneous micelles as bearing a tangible similarity to globular proteins and describes lipid aggregates with catalytic capacity. The polar head groups and hydrophobic tails shown in Section 7 (p. 15), together with the catalytic head groups discussed in Section 9 (p. 18), support the surface-function comparison. Our copy does not establish that the micelles and globular proteins are similar in size. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • Lipids are not chemically inert non-catalytic compounds; lipids and other amphiphiles have considerable catalytic function.

    “Lipids are widely thought of as chemically inert non-catalytic compounds whose role is to form membranes. An important aspect of this misconception is the ‘like it is today’ outlook, which infers amphiphile chemical properties based on the molecule types found in present-day cells.”
  • Macromolecules lining the walls would have moderated the movement of molecules into and out of the microchambers, serving as proto-membranes.

    “Macromolecules lining the walls would have moderated the movement of molecules into and out of the microchambers [64,164]), serving as proto-membranes (Figure 4, step 2c).”
  • The principal capability of membrane vesicles for the early steps of life has been described, and recently it was shown that a possible prebiotic amphiphile (decanoic acid) undergoes distinct binding interactions with nucleobases and proteins, so vesicles may serve as containments for initial metabolic steps and as encapsulated environments for RNA replication.

    “The principal capability of membrane vesicles for the early steps of life has been described on numerous occasions [27,28,29]. Recently, it was shown that a possible prebiotic amphiphile (decanoic acid) undergoes distinct binding interactions with nucleobases and proteins [30,31]. So, at this stage, they may serve as containments for initial metabolic steps and, most prominently, as an ensemble of”

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.
