Magnetochiral phenomena may be responsible for the selection of chiral statesof biomolecules in meteoric environments. For example, the Supernova Amino AcidProcessing (SNAAP) Model was proposed previously as a possible mode ofmagnetochiral selection of amino acids by way of the weak interaction in strongmagnetic fields. In earlier work, this model was shown to produce anenantiomeric excess (ee) as high as 0.014% for alanine. In this paper wepresent the results of molecular quantum chemistry calculations from which$ee$s are determined for the alpha-amino acids plus isovaline and norvaline,which were found to have positive ees in meteorites. Calculations are performedfor both isolated and aqueous states. In some cases, the aqueous state wasfound to produce larger $ee$s reaching values as high as a few percent underplausible conditions.
