Lipids Bilayer Basic structure of plasma membrane. ENERGETICALLY UNFAVORABLE Serine Phosphate Hydrophilic heads interact with water planar phospholipid bilayer with edges exposed to water Hydrophobic tails interact with each other sealed compartment Hydrophilic heads interact with water formed by phospholipid bilayer ENERGETICALLY FAVORABLE The closed structure is stable because it avoids the exposure of the hydrophobic tails to water,which would be energetically unfavorable.
