Phospholipid molecules, composed of fatty acid “tails” and a phosphate “head,” form an inverse micelle in a nonaqueous solution. The phosphate group converts one end of the lipid molecule into a polar, or hydrophilic, group, leaving the preferentially attracted nonpolar, or hydrophobic, end of the molecule to react with the nonaqueous solution
