- Captopril is a drug used to treat high blood pressure and congestiveheart failure.Designate each stereogenic center as R or S.arrow_forwarda.Label the four stereogenic centers in sorbitol as R or S. b.How are sorbitol and A related? c. How are sorbitol and B related?arrow_forwarda.Locate the stereogenic centers in the ball-and-stick model of ezetimibe (trade name Zetia), a cholesterol-lowering drug. b. Label each stereogenic center as R or S.arrow_forward
- Problem 5.27 (a) Label the four stereogenic centers in sorbitol as R or S. (b) How are sorbitol and A related? (c) How are sorbitol and B related? HO H HO H но н но н Н Он Н ОН HO HO но но но н он Н ОН B H OH HO H HO H HO H sorbitol Aarrow_forwarda) Label the hemiacetal in glucosamine, available in overthe-counter remedies for the treatment of osteoarthritis. (b) Label all the other functional groups in glucosamine.arrow_forwardLocate the stereogenic centers in each drug. Albuterol is a bronchodilator—that is, it widens airways—so it is used to treat asthma. Chloramphenicol isan antibiotic used extensively in developing countries because of its lowcost.arrow_forward
- Label each stereogenic center as R or S (Questions a, b and c please)arrow_forwardOne of the analgesics has a chiral center. Which compound is it? One of the two enantiomers is far more effective at reducing pain than the other.arrow_forward(d) Draw the structure of the expected product when monosaccharide B undergo mutarotation upon dissolving in water in the presence of Tollens reagent (AGNO3, NHẠOH). он OH O.

- Give the IUPAC name for attached compound, including the R,S designationfor each stereogenic center.arrow_forward(a) assign R or S configuration to each chiral center, (b) Which compound are enantiomers? (c) Which compounds are diastereomers?arrow_forward(a) Draw a skeletal structure of the anabolic steroid methenolone from the following description. Methenolone contains the tetracyclic steroid skeleton with a carbonyl group at C3, a hydroxyl at C17, a double bond between C1 and C2, and methyl groups bonded to C1, C10, and C13. (b) Add wedges and dashed wedges for all stereogenic centers with thefollowing information: the configuration at C10 is R, the configuration at C13 is S, the configuration at C17 is S, and all substituents at ring fusions are trans to each other. (c) Draw the structure of Primobolan, the product formed when methenolone is treated with CH3(CH2)5COCl and pyridine. Primobolan is an anabolic steroid that can be taken orally or by injection and has been used illegally by well-known Major League Baseball players.arrow_forward
