| Popis: |
The origin of life is still a mystery with many unsolved puzzles. How were molecules created? How did they assemble into large structures? Among the many mysteries, the “chirality” phenomenon upon which amino acids and sugars form is particularly exciting. Single chiral molecules in any chemical system play a very particular role, and these are the only systems where one can be sure that they display 100% enantiomer excess. If this kind of system is a sub-sytem of reaction mixtures where highly sensitive autocatalytic reactions may develop, as for example in the case of the Soai reaction, the presence of this initial chiral molecule can decisively influence the subsequent stereochemical developments. In the work presented here we try to understand how the phenomenon of chirality is related to single molecules, and how this starting situation could influence the outcome of reactions where the product(s) is(are) of high molecular weight, such as synthetic or biological polymers. |
