Question: what does the phospholipid bilayer consist of coursehero?
Answer: A phospholipid consists of a hydrophilic head, having an affinity to water, and two hydrophobic tails, which have no affinity to water. The hydrophilic head has an affinity for water and is, therefore, positioned so that it is oriented outward in the bilayer, toward the intracellular and extracellular fluids.
