Cell Membrane is made up of

The Cell Membrane is made up of glycerophospholipids and proteins and typically described as phospholipid bi-layers. These glycerophospholipids molecules composed of glycerol, a phosphate group, and two fatty acid chains.

Glycerol is a three-carbon molecule that functions as the backbone of these membrane lipids. Within an individual glycerophospholipid, fatty acids are attached to the first and second carbons, and the phosphate group is attached to the third carbon of the glycerol backbone.

Glycerophospholipids are by far the most abundant lipids in cell membranes. Like all lipids, they are insoluble in water, but their unique geometry causes them to aggregate into bilayers without any energy input.
