(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.

- a.) Draw the line angle structural formula for the ester in jojoba wax that is formed from arachidic acid, a 20-carbon saturated fatty acid, and 1-docosanol, CH3 —(CH2)21 —OH. b.) Draw the line angle structural formula for a mixed triacylglycerol that contains two palmitic acid molecules and one oleic acid molecule on the center carbon of glycerol.arrow_forwardGive the IUPAC name.arrow_forwardDraw a structural formula for the one ketone with a carbon chain length of four and the molecular formula C,H120.arrow_forward
- Compounds with nearly identical molar masses often havevery different physical properties. Choose the compound withthe higher value for each of the following properties, and explainyour choice.(a) Solubility in water: chloroethane or methylethylamine(b) Melting point: diethyl ether or 1-butanol(c) Boiling point: trimethylamine or propylaminearrow_forwardCertain omega-3 fatty acids can be found only in animal sources, such as fatty fish. Two of these are eicosapentaenoic acid (EPA) [20:5] and docosahexaenoic acid (DHA) [22:6], both of which are ω-3 fatty acids. DHA has been shown to be important in healthy brain development, so it has recently been added to infant formulas. Breast milk is rich in DHA as long as the mother maintains a healthy diet that includes fish. Draw skeletal structures of the fatty acids EPA and DHA.arrow_forwardMineral oil, a mixture of high molecular weight alkanes, is sometimes used as a laxative. Why are individuals who use mineral oil for this purpose advised to avoid taking it at the same time they consume foods rich in fat-soluble vitamins such as vitamin A?arrow_forward
