(a)
Interpretation: The conversion of given ball-and-stick model of androsterone to a skeletal structure using wedges and dashed wedges around all stereogenic centers is to be stated.
Concept introduction: Steroids, a group of tetracyclic lipids composed of one five-membered ring and three six-membered rings. These rings are lettered by A, B, C, and D. Most of the steroids contain two angular methyl groups. These methyl groups are numbered as
(b)
Interpretation: The conversion of given ball-and-stick model of androsterone to a three dimensional representation using chair cyclohexane rings is to be stated.
Concept introduction: Steroids, a group of tetracyclic lipids composed of one five-membered ring and three six-membered rings. These rings are lettered by A, B, C, and D. Most of the steroids contain two angular methyl groups. These methyl groups are numbered as

- Look up the structure of lisdexamfetamine (Vyvanse), a drug used in the treatment of attention deficit hyperactivity disorder (ADHD). Redraw it and identify all the functional groups present. What is known about itstherapeutic properties?arrow_forwardDraw the structure of cholic acid, showing the rings in their chairconformations, and label each methyl group and hydroxy group asaxial or equatorial.arrow_forwardwhat is the structure of hexane / ethyl acetate 1: 1?arrow_forward
- How many stereogenic centers Tryptophan have? Please encircle it in the drawingarrow_forwardDraw a three-dimensional structure for each compound. Denote the asymmetric carbon atom with an asterisk (*). Draw the mirror image for each structure, and state whether you have drawn a pair of enantiomers of just the same molecule twice.arrow_forwardCholic acid, a major constituent of bile, has the structure shown.(a) Draw the structure of cholic acid, showing the rings in their chairconformations, and label each methyl group and hydroxy group asaxial or equatorial. (Making a model may be helpful.)(b) Cholic acid is secreted in bile as an amide linked to the aminogroup of glycine. This cholic acid–amino acid combination acts asan emulsifying agent to disperse lipids in the intestines for easierdigestion. Draw the structure of the cholic acid–glycine combination,and explain why it is a good emulsifying agent.arrow_forward
- Classify each OH group and halogen in dexamethasone, a synthetic steroid, as 1°, 2°, or 3°.arrow_forwardClassify each structure according to its functional class. For parts C and Dalso indicate if the group is 1 degrees, 2 degrees or 3 degreesarrow_forwardMaltose is a carbohydrate present in malt, the liquid obtained from barleyand other grains. Although maltose has numerous functional groups, itsreactions are explained by the same principles we have alreadyencountered. Label the acetal and hemiacetal carbons.arrow_forward
