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, ฮฑ-hydrogen, protein amino acids over a variety of plausible parent body thermal histories, based on meteorite
Activation energies and Arrhenius frequency factors were calculated for the racemization reaction of four bound amino acids (asp, glu, pro, phe) isolated from sequoia heartwood, by using elevated temperature rate constants. In addition, a first-order rate constant of 2.1 x 10m5 yea+' was calculated
