That, however, isnt the case. Humans convert the S-thalidomide into R-thalidomide once in the body, so it really doesnt matter which enantiomer is taken, it would shoot toxic effects to the babies of the pregnant women anyway. Although the use of Thalidomide for morning sickness and its libellous effects to the babies has been called one of the biggest medical tragedies of modern generation, there was some good to come from finding the mischievous results.
