Ferric salt of the fructose - diphosphate - 1,6, for its preparation and to its use in the preparation of the fructose 1,6 diphosphoric - -

摘要

P & it is described a ferric salt of the fructose - diphosphate - 1,6, which may be precipitated quantitatively in the pure state from mixtures of pdfs and satisfies the formula (3 fe4 pdfs) . For preparing this salt, a ferric salt and an alkaline substance are added to a fermentation broth, which contains the pdfs, then the precipitate is washed thoroughly with water to eliminate the alkali metal salt, and the solid substances are washed, dried or frozen. / p & & p & the ferric salt offers numerous advantages with respect to the calcium salt used until now, and any organic solvent is no longer necessary. It is useful for preparing the fructose - diphosphoric - 1,6, which has a pharmacological activity. / p
