Exist because <double bonds> don't rotate freely. Have different properties of course, unlike <enantiomer>.

Mirror images.

Key exmaple: <d and L amino acids>. Enantiomers have identical physico-chemical properties. But their biological roles can be very different, because an <enzyme> might only be able to act on one of them.


Enantiomer

{disambiguate=materials science}
{wiki}

TODO definition. Appears to be <isomers>

Example:
* the three most table polymorphs of <calcium carbonate polymorphs> are:
  * <calcite>
  * <aragonite>
  * <vaterite>
