Biological Activity

Phosphatidylcholine is a major constituent of cell membranes and pulmonary surfactant, and is more commonly found in the exoplasmic or outer leaflet of a cell membrane. Phosphatidylcholine also plays a role in membrane-mediated cell signaling and PCTP activation of other enzymes.
