Serine Sublimes with Spontaneous Chiral Amplification
Sublimation of near-racemic samples of serine yields a sublimate which is highly enriched in the major enantiomer; this simple one-step process occurs under relatively mild conditions, and represents a possible mechanism for the chiral amplification step in homochirogenesis.
