the data presented demonstrate that , in the iris , carbachol ( 50 microm ) stimulates the rapid breakdown of ptdins ( 4,5 ) p2 into [ 3h ] inositol trisphosphate ( insp3 ) and diacylglycerol , measured as phosphatidate , and that the accumulation of insp3 precedes that of [ 3h ] inositol bisphosphate ( insp2 ) and [ 3h ] inositol phosphate ( insp ) .
