Double layer of phospholipid molecules forming cell membrane.

Barrier structure made up of two layers with hydrophobic tails.

Lipid bilayer containing phosphate group, found in biological membranes.

Main component of plasma membrane surrounding cells.

Structural component of cell membranes.

Selectively permeable barrier for cellular compartments.

Formed by two layers of phospholipid molecules.

Essential for maintaining cell shape and function.

Made up primarily of hydrophobic tails and hydrophilic heads
