stereoisomer

 [ster″e-o-i´so-mer]
a compound showing stereoisomerism.

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. Compare: isomer.

/ster·eo·iso·mer/ (ster″e-o-i´so-mer) one of a group of compounds showing stereoisomerism.

stereoisomer

[stir′ē·ō·ī′səmər]
Etymology: Gk, stereos, solid, isos, equal, meros, part
one of two or more chemical compounds that contain the same atoms linked in the same way but that are organized differently in space. For example, one may be the nonsuperimposable mirror image of the other.

ster·e·o·i·so·mer

(ster'ē-ō-ī'sŏ-mĕr)
