The consistency of chirality in the crucial organic compounds of life, across continents where evolution has run its course in separated regions, has fascinated chemists because it raises more questions than it answers, Did a single chance event set the whole system in motion and replication of chiral molecules gradually spread, for example, the role of only L amino acids in peptides, across the whole planet before the continents separated, was this seeded over the globe in a cosmic event, or is there a fundamental bias in Nature that favours L amino acids and D sugars? The electrostatic energy terms used in quantum mechanical ...
