The three major kinds of cell membrane lipids in animals are phospholipids, glycolipids, and cholesterol. Lipids are water insoluble, but can be extracted with nonpolar solvents like benzene, methanol, or ether. Lipids are non polar so they are soluble in nonpolar environments thus not being water soluble because water is polar. Lipids are a distinct group of compounds, including oils, waxes, steroids, fats and similar compounds that are very much connected by their physical property rather than their chemical property. They are insoluble in water but soluble in nonpolar solvents such as ether, acetone and chloroform.
