Racemic Mixtures: Resolving Enantiomers

Racemic mixtures can be separated, or resolved, into their pure enantiomers by three methods. The first method is to mechanically separate the crystals in such a mixture based on differences in their shapes. This was the method first used by Pasteur, and it is mainly of historical interest. The second resolution method employs enzymes.
