Abstract
Incubation of rat lung microsomes with CDP[Me-14C]choline resulted in formation of radioactive lysophosphatidylcholine and phosphatidylcholine. Evidence is provided which suggests that lysophosphatidylcholine formation cannot be ascribed completely to phospholipase A degradation of phosphatidylcholine. Lysophosphatidylcholine production can be stimulated by addition of monoacylglycerol or diacylglycerol. It is suggested that diacylglycerol is
