Phosphatidylcholine

Phosphatidylcholine (PC) is a phospholipid naturally produced in the liver; however, the body’s synthesis is often insufficient to meet daily needs. Dietary sources of phosphatidylcholine include soy, mustard, sunflower seeds, red meat, whole grains, and eggs.

Phosphatidylcholine plays a critical role in the structure of the cell membrane, which consists of a phospholipid bilayer. This bilayer is composed of:

• A polar outer layer (high energy)
• A nonpolar inner layer (low energy)

Additional components of the cell membrane include cholesterol, sphingomyelin, and phosphatidylcholine itself.

Changes in Cell Membranes with Aging

As the body ages, the composition of the cell membrane shifts, leading to a decrease in phosphatidylcholine and an increase in cholesterol and sphingomyelin. These changes can make cell membranes more rigid and less flexible.

Including foods rich in phosphatidylcholine as part of a balanced diet may help support overall cell membrane integrity and function.
