Variation in the architecture of molecules can cause variable biological effects. give an example of how isomers can vary in their pharmacological effects.

Answer and explanation;

-The pharmacological importance of enantiomers. L-Dopa is a drug used to treat Parkinson's disease, a disorder of the central nervous system. The drug's enantiomer, the mirror-image molecule designated D-Dopa, has no effect on patients.

-The concept of enantiomers is important in the pharmaceutical industry because the two enantiomers of a drug may not be equally effective. In some cases, one of the isomers may even produce harmful effects. This was the case with thalidomide, a drug prescribed for thousands of pregnant women in the late 1950s and early 1960s. The drug was a mixture of two enantiomers.

-One enantiomer reduced morning sickness, the desired effect, but the other caused severe birth defects. The differing effects of enantiomers in the body demonstrate that organisms are sensitive to even the most subtle variations in molecular architecture. Once again, we see that molecules have emergent properties that depend on the specific arrangement of their atoms.

actually the answer is c
