General description

Phosphatidylcholine is the major membrane phospholipid in eukaryotic cells. This structural component of the cellular membrane is the source of the bioactive lipids lysophosphatidylcholine, phosphatidic acid, diacylglycerol, lysophosphatidylcholine, platelet-activating factor, and arachidonic acid.

Application

L-α-Phosphatidylcholine has been used in differential lipid partitioning experiments of xenobiotics and natural compounds to determine trioleoylglycerol (TG) and phosphatidylcholine (PC) coefficients (KTG/PC) for partitioning of lipophilic chemicals.

Biochem/physiol Actions

Phosphatidylcholine serves as a reservoir for several lipid messengers. Phosphatidylcholine is used for the preparation of vesicle suspensions, commonly called liposomes or monolayers.
A major structural phospholipid in brain, comprising approx. 15% of total lipid; primarily localized to gray matter.

Pulmonary surfactant is a complex of phospholipids and proteins lining the alveolar walls of the lung. It reduces surface tension in the alveoli, and is critical for normal respiration. Pulmonary surfactant phospholipids consist mainly of phosphatidylcholine (PC) and phosphatidylglycerol (PG).
