However, by the process known as enantiomeric crossinhibition, the ' wrong ' monomer can attach to a chain (with rate ax) leading to a ' spoilt ' polymer chain which can grow no further, ! In that model, we saw that it was a combination of large fidelity (f) and enantiomeric cross-inhibition (x) which caused symmetry-breaking. Surprisingly, we find the driving force for this to be enantiomeric cross-inhibition in which the addition of a ' wrong-handed ' enantiomer to a growing polymer brings the polymerization to a halt. Therefore, many authors claimed on a possible role of such crystals in enantiomeric pure form as the source of chirality and even homochirality of organic molecules in nature. Ice photochemistry may more easily accommodate the deuterium enrichment, and enantiomeric excesses of the amino acids in meteorites. Thus, in that case the global enantiomeric excess can no longer grow exponentially in time, but only linearly. The obtained results are compared in terms of the achieved enantiomeric separation and mass spectrometric response. We note, however, a consistency in that in all the results, a large enantiomeric cross-inhibition is more favourable for symmetry breaking than a small cross-inhibition. This is, in essence, what is meant by enantiomeric cross-inhibition. Our preliminary analyses results show that a possible enantiomeric excess would be small. Moreover, the addition of a nucleotide of opposite handedness is known to 'spoil' further polymerization (also known as ' enantiomeric cross-inhibition '). The interaction between the mirrored strands is assumed to occur through two separate phenomena : enantiomeric cross-inhibition and enzymatic autocatalysis. A speculation was made in a recent paper about a possible enantiomeric discrimination produced by supernova antineutrinos5. While there are significant enantiomeric differences, the preferred handedness seems to vary between reactions and between amino acids. These perturbations grow locally, leading to patches with enantiomeric excess of either handedness. A hypothesis stating that the advent of membrane phospholipid with enantiomeric glycerophosphate backbones caused the separation of the two lines of descent. The purpose is to reveal and study the possible apparition of an enantiomeric excess on amino acids formed in such experiments. |
