in the final series of experiments , the addition of the phosphoglycerides pc , pe , ps and pa in amounts of 5 or 10 microm caused either no inhibition ( pe , 2 % ) , slight inhibition ( pc , 15 % ) or reasonably significant inhibition ( pa , 20 % and ps , 40 % ) of action of the purified phospholipase a2 on 1-acyl , 2- [ 1-14c ] -oleoyl pi .
