And an argument from analogy is never conclusive, only indicative (at best).
It's effectively saying: A is like B (but not identical), therefore what's
true for A is true for B. It may not be.

HCN may not be enough to produce organic molecules into useful biological
molecules but it (or something with similar properties) in a system
that was producing racemic proteins could act as a racemase.
That would solve most of the difficulties with the enantiomers forming.
It increases the probability of homochiral molecules to about 1/2 from
The problem is all experiments have failed to demonstrate any such
favoritism. Rather, they have uncovered the reason for a lack of favoritism.
The second law of thermodynamics guarantees that even collections of
molecules which begin with some favoritism will degrade to racemic mixtures.
This is more then enough to stymie research and just drop it all together.
