Lipids are biomolecules that are soluble in _______ and insoluble in _______, Water; nonpolar solvents , Nonpolar solvents; water, What is the difference between hydrolyzable and non-hydrolyzable lipids, giving one structural feature that distinguishes them., Hydrolyzable lipids (like fats, oils, waxes, phospholipids) contain ester linkages that can be broken down by hydrolysis to yield smaller molecules (fatty acids + alcohols)., Non-hydrolyzable lipids (like steroids, vitamins, eicosanoids) lack ester linkages and cannot be split by water., Non-Hydrolyzable lipids (like fats, oils, waxes, phospholipids) contain ester linkages that can be broken down by hydrolysis to yield smaller molecules (fatty acids + alcohols)., Hydrolyzable lipids (like steroids, vitamins, eicosanoids) lack ester linkages and cannot be split by water., Why are lipids insoluble in water but soluble in non-polar solvents?, Lipids are insoluble in water because they have long nonpolar hydrocarbon chains with few polar groups., They are insoluble in nonpolar solvents (like chloroform or ether) because of the similar nonpolar interactions (like dissolves like)., They are soluble in nonpolar solvents (like chloroform or ether) because of the similar nonpolar interactions (like dissolves like)., Lipids are soluble in water because they have long nonpolar hydrocarbon chains with few polar groups., Contains no ester linkages, Non-hydrolyzable, Hydrolyzable, Hydrolyzable lipids contain _______ linkages that can be broken by hydrolysis., cis-double bond, unsaturated fatty acid, ester, Contains ester linkages and can be cleaved by aqueous acid/base, Non-hydrolyzable, Hydrolyzable, As the number of cis-double bonds increases, the melting point _______., Increases, Decreases , Nothing changes , Are waxes, triacylglycerols, and phospholipids hydrolyzable or non-hydrolyzable, Hydrolyzable, Non-hydrolyzable, An omega-3 fatty acid has its first C=C bond on the _______ carbon from the methyl end, First , Last , Fourth, Third, Are steroids, fat-soluble vitamins, eicosanoids hydrolyzable or non-hydrolyzable, Hydrolyzable , Non-hydrolyzable, Saturated fatty acids have _______ double bonds, while unsaturated fatty acids contain _______ or more., one or more; none, no; one or more, no; two, one or more; two.
