PHOSPHOLIPIDS AS A GOOD SOURCE OF ENERGY :

Phospholipids are a class of lipids having a phosphate group in its molecule. For example: phosphatidylcholine.

1) As the phosphate group in the phospholipid is charged, so lipid mix with both fat and water and make it amphipathic. Therefore, phospholipids make the outer membranes of cells. Phospholipid molecule generally consists of two hydrophobic fatty acid “tails” and a hydrophilic “head” consisting of a phosphate group.

2) Phospholipid membrane allows small molecules such as oxygen and carbon dioxide to pass into and out of the cell.

3) Phospholipids are crucial for digestion.
– In the stomach, phospholipids break fats so that it is easier to digest.
– In the small intestine, the phospholipids in bile help emulsify fats so they can be carried in blood.

4) It helps in energy production as body oxidizes fatty acids and glycerol to produce energy.

5) It is used as energy storage as fatty acids and glycerol that are not oxidized may be stored as fat and stored body fats provide a ready source of potential energy….
