Phosphatidylcholine

Comprises the most abundant phospholipid in eukaryotic cell membranes, playing crucial roles in membrane structure, signal transduction, and lipid transport.

Key Functions:

• Major structural component of cell membranes.
• Serves as a precursor for diacylglycerol and phosphatidic acid in signaling pathways.
• Key component of lipoproteins and bile.
• Essential for lung surfactant production.

Interacting Systems & Components:

• Cell Membrane (major component)
• Lysophosphatidylcholine (product of partial hydrolysis)
• Diacylglycerol (can be formed from)
• Lipoproteins (component of)
• Pulmonary Surfactant (major component)
