Metabolic precursors in astrophysical ice analogs: Implications for meteorites and comets

Academic Article


  • We report the synthesis of complex organic compounds including nicotinic and quinolinic acid, two members involved in the nicotinamide adenine dinucleotide (NAD) biosynthetic pathway, in irradiated astrophysical ice analogs. If delivered to Earth by meteorites and comets, these compounds may have contributed to the origin and early evolution of life.
