Rapid radiolytic degradation of amino acids in the Martian shallow subsurface: Implications for the search for extinct life
Amino acids are fundamental to life as we know them as the monomers of proteins and
enzymes. They are also readily synthesized under a variety of plausible prebiotic conditions …

Prebiotic chiral transfer from self-aminoacylating ribozymes may favor either handedness
Modern life is essentially homochiral, containing D-sugars in nucleic acid backbones and L-
amino acids in proteins. Since coded proteins are theorized to have developed from a …
