Answer:
The common characteristics between fatty acids, triacylglycerols, phosphoglycerols, sphingolipids, polyisoprenoides and sterols are that they are nonpolar substances. Thus, these substances are soluble in nonpolar solvents, unlike water.
Explanation:
Lipids are the most diverse range of biomolecules that have a hydrocarbon chain as the backbone. The hydrocarbon chain is formed of series of carbon atoms and balanced by hydrogen atoms. Due to their close electronegativity, the hydrocarbon chain renders the lipid its nonpolar property. Water is a polar solvent, and thus the lipid molecules are not soluble in it. The metabolism of lipids causes oxidation of fatty acids, that in turn generate energy.
