Document Summary
Draw the structure of each of the fol- lowing fatty acids and give the structure its common name: (a) n-dodecanate (b) cis-9-hexadecenoate (c) cis,cis-9,12- Octadecadienoate: fluiditymatters. triacylglycerolsareusedforfuelstorage in both plants and animals. The triacylglycerols from plants are often liquid at room temperature, whereas those from animals are solid. Suggest some reasons for this difference: contrast. What structural features differentiate sphin- golipids from phosphoglycerides: depict a lipid. Draw the structure of a triacylglycerol composed of equal amounts of palmitic acid, stearic acid, and oleic acid. What structural characteristic of lipids accounts for their solubility in organic solvents: like finds like 2. Suppose that a small amount of phospho- lipid were exposed to an aqueous solution. What would be the driving force for the formation of this structure: linkages. Platelet-activating factor (paf) is a phospho- lipid that plays a role in allergic and inflammatory responses, as well as in toxic shock syndrome.
