Stereochemistry is the study of the three‐dimensional structure
of molecules. The cis and trans isomers are forms
of stereoisomers, differing structurally only in
the location of the atoms of the molecule in three‐dimensional
space. Such stereoisomers can have different physical and chemical
properties. Stereochemistry is of particular interest to
biochemists because the reactivity and toxicity of molecules change
with their stereochemistry. Most body reactions are
stereospecific, meaning that receptor sites on
cells accept only molecules with specific spatial arrangements of...
