phospholipase c activity was determined directly by measuring the ca++-dependent conversion of membrane-bound , labeled phosphatidate to diacylglycerol or indirectly by measuring the diacylglycerol-dependent ( brain diacylglycerol content ) formation of phosphatidylcholine in the presence of labeled cytidine diphosphate ( cdp ) choline .
