Question: lipids are insoluble in water because lipid molecules are?
Lipids are insoluble in water primarily because they are hydrophobic, meaning they have a fear of water. The structure of lipids includes long nonpolar chains of carbon atoms, which are hydrocarbons that include mostly nonpolar carbon-carbon or carbon-hydrogen bonds. These nonpolar molecules do not mix with water, which is a polar solvent, because they cannot form hydrogen bonds with the water molecules. This characteristic allows them to form cell membranes and store energy without dissolving in the body's aqueous environment.
