Phospholipids are surprisingly a part of our everyday lives.

The term "phospholipid" may seem a bit unfamiliar.
But in fact, they are found in fish, grains, and even in our bodies!

We even have phospholipids in our bodies!

Current research finds that humans are made up of tens of trillions of cells.
All cells are surrounded and protected by a membrane called the cell membrane.
This membrane is in fact made of phospholipids.

Look how tiny phospholipids are!

Phospholipids are only a few nm (nanometers) in size.
Suppose the Earth were 1 meter in size. By comparison,
phospholipids would be just the size of a ping-pong ball!

Size of the earth: about 12,742km
Assuming a ping-pong ball 4cm in size
