Describe how phospholipids are arranged in the cell membrane

The phospholipids are arranged in two layers, called a phospholipid bilayer.

A phospholipid is a kind of lipid molecule that is the principal component of the cell membrane. Lipids are molecules that comprise fats, waxes, and some vitamins, among others. Every phospholipid is composed of two fatty acids, a phosphate group, and a glycerol molecule. While many phospholipids line up, they create a double layer that is characteristic of all cell membranes. They have hydrophobic tails and hydrophilic heads The hydrophilic heads are to the outside and the tails to the inside.
