IP_5pase1 acting as a Substrate in a reaction in  NonOsc_Ca_IP3metabolism Network

Kd is calculated only for second order reactions, like nA+nB <->nC or nA<->nC+nD, where n is number and A,B,C,D are molecules, where as for first order reactions Keq is calculated. Kd for higher order reaction are not consider.
