The Metabolic Fate of Lysolecithin Administered into Rat Duodenal Lumen

The fate of intracardially administered retinyl esters in the rat.

Irrespective of the form of vitamin A fed to rats, it appears in blood almost exclusively as retinyl palmitate, and the liver always stores only this ester. Differences in the fatty acid composition of the dietary fats do not seem to have any influence on the type of retinyl ester absorbed and stored by the rat (Mahadevan & Ganguly, 1961; Mahadevan, Seshadri Sastry & Ganguly, 1963). It was ther...

Fate of porphobilinogen, administered enterally or parenterally, in the rat.

Incorporation of dietary lecithin and lysolecithin into lymph chylomicrons in the rat.

Incorporation of dietary phospholipids into lymph chylomicrons was studied in rats fed corn oil containing either radioactive lecithin or lysolecithin. The specific activity of lecithin-s2P in chylomicrons relative to that in the oil increased directly with the amount of lecithin fed, whereas the lecithin content of chylomicrons was constant. About 40% of the phospholipid in chylomicrons was de...

The Fate of Phospholipid Injected Intrave- Nously into the Rat*

Many attempts have been made to influence the phospholipid content of various organs of the body by the administration of phospholipid. Reports of results obtained upon feeding phospholipids are many and conflicting, one reason being, as pointed out by Sinclair (1934), that it is highly improbable that any intact phospholipid would be absorbed from the intestinal tract. The intravenous injectio...
