In the late 1960s, Langridge and co-workers developed methods, first at Princeton, then at UC San Francisco, to visualize 3D molecular models on the screens of cathode-ray tubes. At the same time Marshall, at Washington University St. Louis, MO, USA, started visuaHzing protein structures on graphics screens.

The separation of a racemic mixture into its enantiomeric components is termed resolution The first resolution that of tartaric acid was carried out by Louis Pasteur m 1848 Tartaric acid IS a byproduct of wine making and is almost always found as its dextrorotatory 2R 3R stereoisomer shown here m a perspective drawing and m a Fischer projection... 

Three years later Robert F Furchgott discov ered that the relaxing of smooth muscles such as blood vessel walls was stimulated by an unknown substance produced in the lining of the blood vessels (the endothelium) He called this substance the endothelium-dependent relaxing factor or EDRF and in 1986 showed that EDRF was NO Louis J Ignarro reached the same conclusion at about the same time Further support was provided by Salvador Moncada who showed that endothelial cells did in deed produce NO and that the l arginine to l citrulline conversion was responsible... 

A more constrained opportunity for nitrate bioremediation arose at the US-DoE Weldon Spring Site near St. Louis, Missouri. This site had been a uranium and thorium processing faciUty, and treatment of the metal had involved nitric acid. The wastestream, known as raffinate, was discharged to surface inpoundments and neutralized with lime to precipitate the metals. Two pits had nitrate levels that requited treatment before discharge, but heavy rains in 1993 threatened to cause the pits to overflow. Bioremediation by the addition of calcium acetate as a carbon source successfully treated more than 19 million liters of water at a reasonable cost (75). 

Although scientists have known since the time of Louis Pasteur (1) that optical isomers can behave differentiy in a chiral environment (eg, in the presence of polarized light), it has only been since about 1980 that there has been a growing awareness of the implications arising from the fact that many dmgs are chiral and that living systems constitute chiral environments. Hence, the optical isomers of chiral dmgs may exhibit different bioactivities and/or biotoxicities.
