Arachidonic acid mobilization among phospholipids in murine mastocytoma P-815 cells: role of ether-linked phospholipids.

The ethanolamine-containing glycerophospholipids, choline-containing glycerophospholipids, and phosphatidylinositol fractions are major sources of arachidonic acid in murine mastocytoma P-815 cloned cells. The choline-linked fraction contained high arachidonic acid contents in 1-O-alkyl-2-acyl- (18%) and 1,2-diacyl-sn-glycero-3-phosphocholine (11%), with smaller amounts in 1-O-alk-1'-enyl-2-acy...

Biosynthesis of Prostaglandins from Arachidonic Acid in Guinea Pig Lung

The prostaglandins constitute a class of physiologically active compounds with a widespread occurrence in animal tissues (see References 2 and 3). Previous studies have led to the determination of their structures (4-S), and more recent investigations have shown that they can be formed enzymatically from the essential fatty acids (7,8). It was thus shown that in homogenates of vesicular glands ...

Arachidonic acid mobilization among phospholipids in murine mastocytoma P-815 cells: role of et her4 in ked phospholipids

Abrtract The ethanolamine-containing glycerophospholipids, choline-containing glycerophospholipids, and phosphatidylinmitol fractions are major sources of arachidonic acid in murine mastocytoma P-815 cloned cells. The choline-linked fraction contained high arachidonic acid contents in 1-0-alkyl-2-acyl(18%) and 1,2-diacyl-sn-glycero-3-phosphocholine (ll%), with smaller amounts in l-O-alk-l'-enyl...

Turnover of arachidonic acid in the major diacyl and ether phospholipids of human platelets.

In this work, the uptake and release of [3H]arachidonic acid by the diacyl and ether species of phosphatidylcholine (PC) and phosphatidylethanolamine (PE) in human platelets were studied. Uptake of [3H]arachidonic acid into 1,2-diacyl-PC and 1,2-diacyl-PE was much greater than into the ether phospholipids of the same class. In [3H]arachidonoyl-labeled platelets stimulated by thrombin, there was...
