Oxygen isotopes in achondrites (above) and primitive achondrites (below). The 8 notation and units are explained in the caption for Figure 6.4. Most achondrites define mass fractionation lines parallel to, but slightly offset from the terrestrial line. Aubrites and lunar samples plot squarely on the terrestrial line. Primitive achondrites generally do not define oxygen mass fractionation lines, but are scattered and resemble their chondrite precursors. 

In any event, the recent growth of the area of enantioselective transformations with chemical catalysts and enzymes has greatly enhanced the overall potential of organic synthesis. Now, asymmetric synthesis of single enantiomers is becoming a common practice in laboratories (56). This volume will focus primarily on enantioselective transformations aided by substoichiometric amounts of chiral compounds. This chemistry is still young and primitive but is full of promise. See (57)...
