The role of chirality in the origin of life
摘要：
The role of chirality in the theories that determine the origin of life are reemphasized—in particular the fact that almost all amino acids utilized in living systems are of the l type. Starting from Z 0 interactions, I speculate on an explanation of the above fact in terms of quantum mechanical cooperative and condensation phenomena (possibly in terms of an e-n condensate where the e-n system has the same status as Cooper-pairing), which could give rise to second-order phase transitions (including d to l transformations) below a critical temperature T c . As a general rule, T c is a low temperature. From this, it is conceivable that the earth provided too hot a location for the production of l amino acids. I suggest laboratory testing of these ideas by looking for the appropriate phase transitions.
