The fate of intravenously administered egg yolk phospholipides in dogs

1. 1. P32-labeled egg yolk phospholipides disappeared from the blood-stream of dogs with an initial half-time of 6–8 hr., which is similar to that for native plasma phospholipides. 2. 2. Most of the phospholipides remaining from 6 to 24 hr. after injection of the egg yolk were found in the liver, with relatively small amounts in lung or spleen. 3. 3. In the 24-hr. period studied there appeared evidence of continuous breakdown of the egg yolk phospholipides.
