Multiple Choice QuestionMany drugs are chiral molecules, which means that two enantiomers of a given drug molecule are possible. Which general statement best describes the biological activities of two enantiomers of a given drug?Multiple choice question.The two enantiomers will always have the same biological activity.The two enantiomers will always have clearly different biological activities.The enantiomers may have similar activities or different activities.

How is it possible that the two enantiomers of a chiral drug can have different biological activities?Multiple choice question.Biological targets are also chiral, and will therefore "fit" differently with the two enantiomers of a chiral drug.One enantiomer of a chiral drug is often missing the necessary functional groups to interact with a biological target molecule.One enantiomer of a chiral drug is typically more soluble than the other in biological fluids, and is thus better able to reach the target.

Biological molecules such as cell receptor proteins are chiral molecules. As a result, the two enantiomers of a chiral drug ______.Multiple choice question.will often have different biological activitieswill interact with the target in the same way

Fill in the Blank QuestionFill in the blank question.The two enantiomers of a chiral compound can have different activities. For example, one enantiomer of thalidomide has sedative properties, while the other enantiomer is a teratogen.

Multiple Choice QuestionThe two enantiomers of a chiral molecule can have completely different odors. Why is this possible?Multiple choice question.Since the two enantiomers of a chiral molecule have different functional groups, they will interact differently with smell receptors.Since the two enantiomers of a chiral molecule have different physical properties, they vary in their abilities to reach smell receptors.Since smell receptors are themselves chiral, they will interact differently with two enantiomers.

Which of the following statements is not true regarding pairs of enantiomers?
