ster·e·o·i·so·mer

(ster'ē-ō-ī'sō-mĕr), A molecule containing the same number and kind of atom groupings as another but in a different arrangement in space; the stereoisomers are not interconvertible unless bonds are broken and reformed, by virtue of which the molecule exhibits different optic properties, for example, as between d- and l-amino acids, or 5α- and 5β-steroids.
