Les phospholipides de al cellule hépatique. Interprétation fonctionnelle de leur renouvellement

The phospholipids of the rat hepatic cellular fractions exhibit a great similarity in what concerns both their nature, essentially lecithins and phosphatidylethanolamines, and their constitutive fatty acids, characterized by the preponderance of stearic and arachidonic acids.

This similarity is related to a common physiological significance: achievement of lamellar layers as well in the floating free fat lipidic particles, the diameter of which is about 250 Å, emulsified in the cytoplasm, as in the mitochondria and the endoplasmic reticulum lipoproteic membranes.
