The Newcastle University research output collection, currently available on ePrints, will shortly be moving to a new open repository platform, Figshare. To prepare for the data migration we have paused adding new content to ePrints, and will resume once the new repository is launched. During this time you will continue to have access to ePrints (but no new content will appear). We will share updates here when available.

Abstract

Simultaneous measurements with magnesium ion-selective and pH glass electrodes have been used for determination of the stability constants of magnesium ions with various biologically relevant ligands by alkalimetric titration under physiological conditions (37-C, I=0.15 mol·dm-3). New systems were investigated: magnesium with pyroglutamate, pyridoxine and HEPES, along with citrate, lactate, glycinate, aspartate and glutamate. For comparison, calcium stability constants with the same ligands were determined similarly, using calcium ion-selective and pH glass electrodes. Ligand protonation constants, necessary for the calculation of the metal complex formation constants, were also determined. © 2009 Springer Science+Business Media, LLC.
