Metal and Hydrogen-Ion Binding Properties of O-Phosphoserine
As pointed out by Mellander1, organic phosphoryl compounds derived from phosphoproteins may behave as effective chelating agents and therefore may be of great biological importance. For the study of the chelating ability of such compounds, synthetic model substances of similar structure are under investigation. Apparent ionization constants of synthetic O-phosphoserine, and apparent stability constants of some metal complexes of that compound have been examined.
