Mg-ATP Calculator v1.3 using constants from Theo Schoenmakers' Chelator
FIND FREE Mg       FIND TOTAL Mg        FIND ATP (given T&F)       FIND ATP (given B&F)
Temperature = C       pH =       Ionic = N

Schoenmakers, Visser, Flik and Theuvenet, BioTechniques v12, #6 (1992) 870-879, CHELATOR: An Improved Method for Computing Metal Ion Concentrations in Physiological Solutions. [see downloads to retrieve a copy of this program]

NOTE: The stability constants and deltaH values & method are the same as in Theo's paper, but the Ionic correction is not.

Gives slightly different results than Theo's Chelator program.

You can save the source for this page, edit and use it to do different calculations. See comments in source.

Calculations above the buffer range of a metal/chelator can result in a convergence error in Find Free mode.
