This video presents and explains cell membrane structure and the role of Phospholipids. (Biomaterials Engineering)
A cell membrane is a self-replicating molecular system that can protect itself by encapsulating the replication process and the replication information to shield it from the external environment.

In order to encapsulate the molecular replication information, the evolving biological system implements a barrier using the molecules available to it.

Phospholipids are modified lipids. A phosphate (PO4-) replaces one of the three fatty acids normally found on a lipid. This is an amphipathic molecule, having hydrophilic, polar "head" and two hydrophobic, nonpolar "tails". Under certain conditions molecules of this type can self assemble into bilayers.

In a water environment, the molecular structure of phospholipids results in their aggregation into a two-dimensionally extended fluid structure known as a “lipid bilayer”. The polar “head” interacts with water, while the non-polar tails interact with themselves.

The phospholipid bilayer behaves as a two-dimensional fluid interface that can act as a semi-permeable membrane. When folded onto itself, it encloses an interior volume that is separated from the exterior by the membrane.
