two subsequent dephosphorylations occur adjacent to the D-5 hydroxyl group to yield myo-inositol-1,2,3-trikisphosphate as the final product, rates of removal of the second and third phosphates are significantly lower, possibly due to reduced specificity for IP5 and IP4 and inhibition by the phosphate released, IP4: only one isomer, either I-1,2,3,4-P4 or its enantiomer I-1,2,3,6-P4, no further hydrolysis of IP3 |
