Concept explainers
Stanozolol is an anabolic steroid that promotes muscle growth. Although stanozolol has been used by athletes and body builders, many physical and psychological problems result from prolonged use and it is banned in competitive sports.

- Draw the structure of A, an intermediate in the synthesis of the antipsychotic drug risperidone. Explain why three rings in risperidone are considered aromatic.arrow_forwardAmino acids such as glycine are the building blocks of large molecules called proteins that give structure to muscle, tendon, hair, and nails. a.) Explain why glycine does not actually exist in the form with all atomsuncharged, but actually exists as a salt called a zwitterion. b.) What product is formed when glycine is treated with concentratedHCl?c.) What product is formed when glycine is treated with NaOH?arrow_forwardWhy is an alkylamine more basic than ammononia?arrow_forward
- Quinapril (trade name Accupril) is used to treat high blood pressure and congestive heart failure. One step in the synthesis of quinapril involves reaction of the racemic alkyl bromide A with a single enantiomer of the amino ester B. (a) What two products are formed in this reaction? (b) Given the structure of quinapril, which one of these two products is needed to synthesize the drug?arrow_forwardCould you explain why the highlighted group on the right side of the double bond has a higher priority than the lower group on the right side of the double bond.
