Meteorites may have contributed amino acids to the prebiotic Earth, affecting the global ratio of right-handed to left-handed (D/ L) molecules. We calculate D/ L ratios for seven biological, Ξ±-hydrogen, protein amino acids over a variety of plausible parent body thermal histories, based on meteorite
