Chirality and Chiral Separations

Chirality and Chiral Separations. Fischer Projections and the DL Nomenclature System : This was invented by Fischer in 1891. It works by having horizontal bonds in front of the plane and vertical bonds behind the plane. Still used for sugars, but generally discouraged.
