kinetics of hydrolysis of the radioactive substrates were determined by measuring the 3h radioactivity retained in the aqueous phase due to free choline and phosphocholine and the 3h and 14c radioactivity recovered in the organic phase due to the released diacylglycerols and phosphatidic acids and the residual phosphatidylcholines .
