In the phospholipid bilayer, transmembrane proteins, which are also known as integral proteins, are embedded. These essential proteins play an important role in transporting molecules across cell … WebTo make a phospholipid molecule into a detergent, you would have to make its hydrophilic head larger or remove one of its tails so that it could form a micelle. Detergent molecules also usually have shorter hydrocarbon tails than phospholipid molecules.
