How are the tails and heads of membrane phospholipids oriented in their environment? a. The hydrophobic heads are oriented towards each other and the hydrophillic tails are oriented towards the extracellular fluid and the intracellular fluid.
Phospholipids align themselves in a tail-to-tail formation with their heads facing outward which creates a double layer membrane. This bilayer structure is used by cells throughout the body for outer membranes as well as for structures inside each cell.Anatomy of a phosphatidylcholine molecule.nlike phosphates, which are attracted to water (hydrophilic), fatty acids are repelled by water (hydrophobic). It is this very love/hate relationship with water that allows phospholipids to form cellular membranes â and liposomes as well.
