Origin of stereoisomer¹

First recorded in 1895–1900; stereo- + isomer

Example Sentences

The enzyme monoamine oxidase recycles one stereoisomer back to the imine, which is therefore eventually all converted into the other stereoisomer.

From Nature

The authors went on to convert the stereoisomer into a variety of biologically active molecules and key intermediates that have been used to prepare such molecules, thereby highlighting the potential application of their chemistry for preparative organic synthesis.

From Nature

Specifically, Evans is interested in enantiomers, a specific class of stereoisomer that involves mirror images of the same molecule.
