The origin of chirality is still not fully understood, and speculation about where and how "enantiopure" life emerged from the primordial soup of abiotic mixtures of racemic molecules is very well reviewed . One of the main conclusions is that all chiral molecules are formed in both enantiomers (racemates), suggesting that the symmetry imbalance between the two possible stereoisomers arose later (racemic/skacalemic/enantiomerically pure) . For example, Fiore et al. demonstrated that a racemic and scalemic mixture of R-1-palmitoyl-2oleoyl-glycero-3-phosphocholine (R-POPC) and S-POPC formed stable membranes similar to those made from homochiral R-POPC .
