(a)
Interpretation: A skeletal structure of the anabolic steroid
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 addition of all wedges and dashed wedges for all stereogenic centers to steroid
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

- How many degrees of unsaturation does in the following drugs contain? mefloquine (antimalarial drug), C17H16F6N2Oarrow_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_forwardDraw the following Lipids in: A) Condensed (detailed) Structure, B) its Block Diagram. C) Show/Indicate the type of linkages per structure (put an arrow). 6) Cholesterol ( use steroid fused ring system with -OH group at C3, double bond at C5, 2 methyl group at C10 & C13, and an 8-Carbon branched side chain at C17)arrow_forward
- For each of the following compounds,determine whether each is optically active. For optically active compounds, identify the chiral carbon: ethane, 2-chloro-2-methylbutane, CH3CH(NH2)COOH, CH3CH2CHClCH3and CH3CH2CH2CH3. And for non-optical active compounds, just provide the structure of the compoundarrow_forwardDraw molecules for the formula C5H10O with functional group alcohol and an ether with an R chiral center.arrow_forwardIs the methyl group at the junction of rings C and D axial or equatorial to ring C?arrow_forward
- Draw the organic products formed when each compound is treated with H2, Pd-C. Indicate the three-dimensional structure of all stereoisomers formed.arrow_forwardIn the synthesis of cholesterol, acetyl-CoA is converted to 2-methyl-1,3-butadiene. Molecules of 2-methyl-1,3-butadiene are then joined to give the carbon skeleton of cholesterol. Draw the condensed structureof 2-methyl-1,3-butadiene. How many carbon atoms does cholesterol contain? What minimum number of 2-methyl-1,3-butadiene molecules is required to make one molecule of cholesterol?arrow_forwardWrite structural formulas for all ketones with the molecular formula C6H12O and give each its IUPAC name. Which of these ketones are chiral?arrow_forward
