Enantiomerism - enantiomerism

Japanese: エナンチオ異性 - エナンチオいせい(英語表記)enantiomerism
Enantiomerism - enantiomerism
When stereoisomers are in a non-superimposable mirror image relationship (Figure 1), they are in an enantiomeric relationship and are called enantiomers. A necessary and sufficient condition for a molecule (and not just molecules, but all objects) to have enantiomers is chirality (the existence of a mirror image relationship). Stereoisomers that are not enantiomeric are called diastereoisomers. According to this classification, stereoisomerism is broadly divided into enantiomerism and diastereoisomerism.

Japanese:
立体異性体が互いに重なり合わない鏡像の関係(図1)にあるとき,両者はエナンチオ関係にあり,エナンチオ異性体であるという。ある分子に(分子に限らずすべての物体に関しても)エナンチオ異性体が存在するための必要十分条件はキラリティ(鏡像関係が成り立つこと)である。エナンチオ関係にない立体異性体を互いにジアステレオ異性体であるという。この分類によると,立体異性はエナンチオ異性とジアステレオ異性に大別される。
