Classical mechanisms proposed for the transition from racemic geochemistry to homochiral biochemistry in terrestrial evolution generally ascribe to chance the particular handed choice of the L-amino acids and the D-sugars by self-replicating systems. The parity-violating weak neutral current interaction gives rise to an energy difference between a chiral molecule and its mirror-image isomer, resulting in a small stabilization of the L-amino acids and the L-peptides in the α-helix and the… 
Chirality and the Origins of Life
Molecular asymmetry is examined in present life, and in prebiotic systems. The origin of chirality has been ascribed to a chance choice of the initial enantiomer or to a universal disymmetric force.
Parity-violating energy differences of chiral minerals and the origin of biomolecular homochirality
The biochemistry of terrestrial organisms is based on chiral (handed) molecules, with one of the two possible series of enantiomers (mirror-image isomers) being predominant. Specifically, terrestrial

It is argued that the phospholipid glycerol headgroups of archaea and bacteria are both exclusively homochiral, and that the reason for this “dual homochirality” was a simple evolutionary choice at the independent origin of the two synthesizing enzymes.
Nuclear β-decay and the origin of biomolecular chirality
The origin of homochirality in terrestrial life has long been debated1. Asymmetric decomposition of racemic mixtures of bio-molecules by longitudinally polarized β-rays has been described as a

This work provides a unified explanation for the origin of homochirality in proteins and DNA using helical secondary structures as the root cause, and ratifies the Principle of Chirality Hierarchy, where chirality of a higher hierarchy dictates that of lower ones.
Nucleotide-catalyzed conversion of racemic zeolite-type zincophosphate into enantioenriched crystals.
Chirality in the inorganic system often depends on the crystallization process which allows the generation of chirality through the organization of achiral inorganic units into the enantiomorphous space group, although statistical fluctuations may occasionally result in enantioenriched bulk samples.
Theories on the Origin of Biomolecular Homochirality
From the discovery of dissymmetric crystals by Louis Pasteur in 1848, the conclusion was drawn that there exist dissymmetric molecular structures [1]. Their occurrence was explained by allpervasive
Helix Generation, Amplification, Switching, and Memory of Chromophoric Polymers
The origin of biomolecular handedness known as homochirality in the animate world may be oneof the most puzzling issues among scientists. The cooperativity of amplification, switching, andmemory in
Amplification of chirality based upon the association of nucleic acid strands of opposite handedness
SummaryIt is proposed that nucleotide strands of opposite handedness may strongly associate and thereby provide the key step of a mechanism for the amplification of a small enantiomeric excess in an
Asymmetry through the eyes of a(nother) chemist
Abstract Mechanism of chiral recognition is one of the most exciting problems in organic chemistry and biochemistry. Starting with a model of three-point interaction between two individual molecules,

There is an alternative “cybernetic” mechanism, a spontaneous generation and self-propagation of asymmetry as a consequence of kinetic bistability in the course of the evolution of open systems.
The parity-violating energy difference between enantiomeric molecules
Abstract The parity-violating weak neutral current perturbation of the electronic energy has been calculated, by ab initio methods, for the (S)-isomer of hydrogen peroxide over a range of gaussian

Experimental attempts for the study of the origin of optical activity on earth
Optical activity of natural compounds is a characteristic of our living world which is based on the asymmetry of the molecular set-up. It is hard to realize a biological cell which would be
