β¦ Synopsis
Through the a&on of rhe panty-~olating weak interactions, a chiral mdecute and its enantiomer are expected to have equilibrium stt-uc~ures which slightly deviate from an exact mirror-image relationship. II is found that such deviations. and the resulting small diMerenccs in the electromagneGc interactions within enantiomeric molecules, are insufiicienr to perturb signikandy or counteract the inherent parity-violating energy differences between enantiomers.

Parity violation at the level of terrestrial biopolymers, as seen in proteins, DNAs, and RNAs, and parity violation at the level of nuclear processes, as evident in longitudinally polarized β€-particles and parity-violating energy differences (PVEDs), are discussed and their fundamental importances a
Ab initio calculations show that a biologically important sugar, D-ribose, is energetically stabilized relative to its unnatural Lenantiomer by the parity-violating weak interactions. This preferential stabilization may account for the exclusive adoption of Dribose rather than its L-enantiomer in th
