Concept explainers
(a)
Interpretation: Among the terms triacylglycerol, glycerophospholipid and sphingophospholipids, the term that can be applied to the given characterization has to be predicted.
Concept introduction: Triacylglycerol is produced by the reaction of one molecule of glycerol and three molecules of fatty acid. Glycerophospholipids are basically made up of two fatty acids, a phosphate group which is esterified to glycerol and an alcohol group which is esterified to the phosphate group. In sphingophospholipids, the platform molecule is sphingosine to which one fatty acid and one phosphate group are attached. An alcohol is attached to the phosphate group.
