The parity-violating energy differences between the enantiomers of α-amino acids

Abstract

The parity-violating weak neutral current perturbation of the electronic energy has been calculated, using ab initio methods, for a series of α-amino acids. The WNC energy shifts for these fundamental biomolecules consistently favour the existence of the natural L-enantiomers in preference to the unnatural mirror-image D-enantiomers.
