50 years ago, pregnant women who were prescribed thalidomide for morning sickness gave birth to children with birth defects. thalidomide is a mixture of two enantiomers; one reduces morning sickness, but the other causes severe birth defects. today, the fda has approved this drug for non-pregnant individuals with hansen’s disease (leprosy) or newly diagnosed multiple myeloma, a blood and bone marrow cancer. the beneficial enantiomer can be synthesized and given to patients, but over time, both the beneficial and the harmful enantiomer can be detected in the body. propose a possible explanation for the presence of the harmful enantiomer.
