Ferric glycerophosphate

Other forms of iron which are present in different pharmaceutical preparations are ferric ammonium citrate, ferrous succinate, iron choline citrate, ferrous amionate, iron calcium complex, carbonyl iron, ferric glycerophosphate, haemoglobin, elemental iron, ferrous glycine sulphate, glycerinated haemoglobin, and iron (III) hydroxide polymaltose complex (equivalent to elemental iron).

When these factors were taken into account, and velocities were determined at dilute concentrations of substrate and in the presence of 0.1 M acetate, pH 5.5, as buffer and 0.01 M EDTA, it was possible to determine the Michaelis constants for different substrates. At 37°C these values were as follows a-glycerophosphate, 3.1 mJlf j8-glycerophos-phate, 2.4 mM yeast adenylate, 0.25 mAf phenyl phosphate, 0.15 mAf. The corresponding values for Tmax, the velocity at infinite substrate concentration, were expressed as micrograms of phosphate liberated per minute 0.9, 1.0, 1.0, and 1.0. With phenyl phosphate as substrate, L-( + )-tartrate was found to be a strong competitive inhibitor, with Ki equal to 0.63 X 10" Af. The enzyme was also reversibly inactivated by cupric and ferric ions and by the thiol reagent, p-chlormercuribenzoate.
