Description: In this episode, Dr. James Tour analyzes a false claim of molecular homochiral evolution, asking, in one example, how proteins could become homochiral when no prebiotically relevant route has been shown to synthesize, separate, or polymerize homochiral amino acids. Furthermore, a discussion on the possibility of racemic molecules in cells takes place. Finally, the amazing phenomenon of chiral-induced spin selectivity (CISS) is introduced, and Dr. Tour shows us how this enables the cell to be the amazing efficient machine that it is.
