3. (10 pts) Propofol is a drug that is used for the induction of anesthesia. It is the drug that ultimately killed the singer Michael Jackson. It has the chemical formula of C12H180. It turns out that Propofol and one of its structural isomers have 13C NMR spectra that show only 6 absorbances, with two below 358 and four between 100 and 1508. Both isomers show a strong absorbance in the IR (thin film/DCM) centered around 3450 cm '; the...

Question 5 3 pts The drug chloroquine has been widely used to treat the human parasite malaria. Mutations in the malaria gene pfcrt confer resistance to chloroquine. In some countries, more than 90% of malaria parasites had the pfcrt resistance alleles. When these countries stopped using chloroquine, the frequency of the pfcrt resistance alleles rapidly declined to less than 5% of alleles. Provide an evolutionary explanation for why the drug-resistant version of the pfcrt allele would decline so quickly. HTML...
