Thioesters Provide a Robust Path to Prebiotic Peptides [PDF]
, 2021 The condensation of building blocks into oligomers and polymers was an early and important stage in the origins of life. High activation energies, unfavorable thermodynamics and side reactions are bottlenecks for abiotic formation of peptides. Thioesters

Prebiotic Chemistry of Pluto [PDF]
Astrobiology, 2019 We present the case for the presence of complex organic molecules, such as amino acids and nucleobases, formed by abiotic processes on the surface and in near-subsurface regions of Pluto. Pluto's surface is tinted with a range of non-ice substances with colors ranging from light yellow to red to dark brown; the colors match those of laboratory organic ...

Simple Ion-Gas Mixtures as a Source of Key Molecules Relevant to Prebiotic Chemistry. [PDF]
Molecules, 2021 Very simple chemistry can result in the rapid and high-yield production of key prebiotic inorganic molecules. The two reactions investigated here involve such simple systems, (a) carbon disulfide (CS2) and acetate (CH3COO¯) and (b) sulfur dioxide (SO2 ...
