What Is The Origin Of Chirality In Nature?

The molecules of life are for the most part chiral, and in living systems, they are almost always enantiomerically pure. In addition, groups of biomolecules are generally homochiral, all amino acids have the same sense of chirality and all sugars have the same sense of chirality.

In 1848, Pasteur deduced that his dissymmetry or the “property by which objects differ only as an image in a mirror differs from the object that produces it” had a molecular basis and proposed that the observed biomolecular homochirality has its origin in the di-symmetric forces of Nature.
