Attrition-induced spontaneous chiral amplification of the γ polymorphic modification of glycine
Abstract
Glycine is the simplest achiral amino acid that undergoes
spontaneous mirror symmetry breaking when it crystallizes in its
chiral γ-polymorphic modification. As a result of Ostwald
ripening, its racemic mixture stochastically becomes optically
active. The sense of the resulting handedness can be controlled by
addition of one enantiomer of a simple chiral amino acid, the
alanine.
