What are phospholipids?
What do they do?
Phospholipids are responsible for keeping cells healthy. They do that by only allowing certain molecules to pass through, enter or exit the cells. Molecules that dissolve in fat can easily move through, but those that dissolve in water cannot. Some molecules, such as oxygen, carbon dioxide, and urea, can easily move through the cell membrane. This helps keep the contents of the cell working properly and separates the inside of the cell from the surrounding environment.
Phospholipids can be broken down in the cell and be used for energy whenever the body needs them. In addition, they can be split into smaller molecules, called chemokines, to produce protein or migrate cells to different areas of the body.
Additionally, they can be used in lungs and in joints lubricating cells.
Some pharmaceuticals, such as Valium, use phospholipids to help deliver the drug to the affected areas. This is because they are easily absorbed by the body
On the other hand, phospholipids are also used as emulsifiers in the food industry. They are commonly found in foods like mayonnaise, soybeans, cotton seeds, and corn.« Back to Glossary Index
