WebbA chirality center is also called a chiral center or an asymmetric center. Some sources use the terms stereocenter , stereogenic center , stereogenic atom or stereogen to refer exclusively to a chirality center, [15] [17] [19] while others use the terms more broadly to refer also to centers that result in diastereomers (stereoisomers that are not enantiomers).
