ScholarlyArticle: "γ-Ray Driven Aqueous-Phase Methane Conversions into Complex Molecules up to Glycine" (2024) https://onlinelibrary.wiley.com/doi/10.1002/anie.202413296 https://onlinelibrary.wiley.com/doi/10.1002/anie.202413296 : > Abstract: γ-Ray is capable of driving an aqueous-phase CH4+H2O+O2 conversion selectively into CH3COOH via ⋅CH3 and ⋅OH radical intermediates, and driving an aqueous-phase CH3COOH+NH3 conversion into NH2CH2COOH via ⋅CH2COOH and ⋅NH2 radical intermediates. Such γ-ray driven aqueous-phase methane conversions probably play an important role in the formation network of complex organic molecules in the universe, and provides a strategy to convert abundant CH4 into value-added products at mild conditions.

  Glycine: https://en.wikipedia.org/wiki/Glycine https://en.wikipedia.org/wiki/Glycine : > Glycine (symbol Gly or G;) is an amino acid that has a single hydrogen atom as its side chain. It is the simplest stable amino acid (carbamic acid is unstable). Glycine is one of the proteinogenic amino acids. It is encoded by all the codons starting with GG (GGU, GGC, GGA, GGG). [8]

  A terrestrial life origin hypothesis: gamma radiation mutated methane (CH4) into Glycine (the G in ACGT) and then DNA and RNA.
