This FR CRNR suggests that there may be numerous points and mechanisms for stereochemical amplification in the FR, suggesting this may be the point of stereochemical enrichment. The CRNR presented here can likely be modified to predict places where enantiomeric symmetry breaking can occur. Such symmetry-breaking effects have been observed in carbonaceous chondrites with respect to products which are either direct products of FR-like chemistry or derived from reactions which use FR products as inputs , though the existence and physical source of such possible enantio-enrichment remains to be explored (see also ).
