Phosphatidylcholine is the most abundant among the phospholipids. It represents 35% of the phospholipids in the soya bean, and almost 70% of those in egg yolk.
Phosphatidylcholine is the most important choline carrier for the organism. Its assimilation is 3 times higher from food phosphatidylcholine than with the choline chloride frequently used.
Choline is sometimes considered to belong to the group B vitamins. It is an important component of cell membranes and it intervenes in lipid metabolism. Choline is considered as an essential nutrient since 1998 in the United-States.
Choline is also a precursor of acetylcholine, a neurotransmitter involved in muscular control and memory processes.
As an essential component of hepatocyte membranes, phosphatidylcholine helps to maintain the resistance and regeneration potency of the liver necessary to its detoxification function. By doing this, it helps the organism to control stress and resist to smoke and alcohol effects.
Phosphatidylcholine is a natural solubilization agent for fats. It influences the transport of cholesterol in the blood and has anti-cholesterolemic and anti-triglyceridemic activities. In synergy with the B12 vitamin and folic acid, PC regulates the blood homocystein content and protects against cardiovascular disease.
