upon the addition of ionophore a23187 , differentiated cells , and not uninduced ones , released [ 14c ] arachidonate from prelabeled phospholipids including ether-linked phosphatidylcholines , formed both 3h-labeled 1-o-alkyl-2-lyso-sn-glycero-3-phosphocholine ( alkyllyso-gpc ) and [ 3h ] alkylacetyl-gpc from endogenous 3h-labeled 1-o-alkyl-2- ( long chain ) acyl-sn-glycero-3-phosphocholine ( alkylacyl-gpc ) , and incorporated exogenously added [ 3h ] acetate or [ 3h ] alkyllyso-gpc into alkylacetyl-gpc .
