  Stereochemistry - Wikipedia, the free encyclopedia
Stereochemistry, a subdiscipline of chemistry, involves the study of the relative spatial arrangement of atoms within molecules.
Stereochemistry is a hugely important facet of chemistry and the study of stereochemical problems spans the entire range of this subject: organic, inorganic, biological, physical and supramolecular chemistry.
Stereochemistry includes methods for determining and describing these relationships; the effect on the physical or biological properties these relationships impart upon the molecules in question, and the manner in which these relationships influence the reactivity of the molecules in question (dynamic stereochemistry).

stereochemistry, study of the three-dimensional configuration of the atoms that make up a molecule and the ways in which this arrangement affects the physical and chemical properties of the molecule.
Central to stereochemistry is the concept of isomerism.
Stereochemistry is particularly important in biochemistry and molecular biology.

 Introduction
Terminology related to techniques used in the determination of stereochemistry are largely excluded as well as terms used to describe reaction mechanisms.
When the IUPAC Commission on Nomenclature of Organic Chemistry prepared section E: Stereochemistry (Recommendations 1974) [1] the document was primarily intended to describe the naming of stereochemical features as part of the overall nomenclature of organic compounds.
The stereochemistry due to substituents attached to a ring should not be shown at a re-entrant angle [marked with an asterisk on (5); although this is suitable for a carbonyl or N-methyl].

Back then, "everything you wanted to know about stereochemistry" fit into 488 pages, and the material could be covered in a single course.
Most aspects of stereochemistry are covered, although polymer stereochemistry, transition-state stereochemistry, and the Woodward-Hoffmann rules are examples of topics omitted.
The vocabulary of stereochemistry is full of compound words with very carefully defined meanings.

 Stereochemistry   (Site not responding. Last check: 2007-10-19)
Stereochemistry is the study of molecules in three dimensions.
The deciding factor for whether a biological reaction will occur is the fit between the substrate(s) and the binding site(s) on the enzyme.
Note: To really get a feel for molecules in 3 dimensions, you may want to use a chemistry modeling set to build yourself models of molecules as we go along.

 Stereochemistry
One aspect of stereochemistry is stereoisomers: same chemical formula but differ in the way atoms oriented in space.
The history of stereochemistry begins in 1815 when Biot performed experiments using "polarized light." Ordinary light consists of light vibrating in numerous planes.
Each of the optically active components had properties identical to tartaric acid (density, melting point, solubility, etc.) except that one of the components rotated the polarized light clockwise (+) while the other component rotated the polarized light by the same amount counterclockwise (-).

 STEREOCHEMISTRY
Authors tend to let their imagination run wild in the invention of new (and often unneeded!) terminology, making life difficult for the reader who, of course, is not familiar with the newly invented terms.
In the latter case ("stereochemistry of a reaction," e.g., retention, inversion, racemization), the proper expression is "steric course" (of the reaction).
While the pharmacology of the two enantiomers was correctly established,9 it was discovered recently10 that thalidomide is racemized not only in vitro but even more rapidly in vivo so that even if the pure eutomer had been administered, it would quickly have been partially converted into the dangerous teratogenic distomer.
