Functions
Phospholipids serve various functions apart from their role in providing structure and permeability. Research has identified three types of phospholipids, each with multiple functions. These essential compounds play a vital role in various processes throughout the body, including the lungs, joints, gastrointestinal tract, and peritoneum.
Phosphatidylcholine: The Vital Phospholipid
Phosphatidylcholine (PC) is a crucial phospholipid found abundantly in mammalian cells. It is synthesized in the body through two pathways. The first pathway relies on choline, a nutrient that the body produces in small quantities but also requires dietary supplementation to prevent deficiencies. The liver relies on PC for the secretion of very-low-density lipoproteins, which transport fat energy to various organs. Moreover, PC aids in the absorption of fat-soluble nutrients in the intestines. In cases of choline deficiency, the significance of the second pathway for PC synthesis becomes even more pronounced.
