摘      要:Acylation of 1- O -(1′-alk-1′-enyl)-glycero-3-phosphorylcholine by long chain acyl thiol esters of coenzyme A to form plasmalogens was catalyzed by enzymes from erythrocytes and muscle. The alkenyl acyl phosphoglycerides produced were the type of plasmalogen most commonly present in mammalian tissues. Enzymes catalyzing this reaction are located in membrane fractions that also contain acyl transfer activity for other phospholipids. Acyl transfer rates with oleoyl-, linoleoyl-, and arachidonoyl-CoA were 13, 27, and 27 mµmoles per min per mg of protein, respectively, with the acyl analogue that forms lecithin, whereas they were 1, 9.4, and 4.7, respectively, with the alkenyl derivative that forms plasmalogen.
