these results indicate that the majority of insp3 liberated by phospholipase c in stimulated platelets must be the non-cyclic ins ( 1,4,5 ) p3 in order to allow rapid phosphorylation by ins ( 1,4,5 ) p3 3-kinase to ins ( 1,3,4,5 ) p4 and then dephosphorylation to ins ( 1,3,4 ) p3 by 5-phosphomonoesterase .
