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.
Un fosfolípido estructural principal del cerebro, que constituye aproximadamente el 15% de los lípidos totales; localizado principalmente en la materia gris.

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).

Octanol-1/water partitioning currently provides the most widely used model system to simulate both phospholipid target lipids and triglyceride storage lipids. A differentiation between the two lipid classes is now achieved by making use of a water-induced lipid phase separation. Coefficients
