<p>#CMT# #/CMT# The proposal is concerned with the metal complexes of poligalacturon acid which also contains M-X-M' structural unit, and their manufacture. M and M' stand for identical or different essential metals or trace elements, preferably with a valency of one, two or three, metals in Groups I-III of the Periodic Table, or transitional metals, especially and preferably iron, zinc, magnesium, copper, chromium, molybdenum, cobalt, nickel, manganese, lithium, sodium, potassium or calcium, using one or in some cases more of these. X is selected from -O-, -O(H)-, O(R')-(R' = poligalacturonat-chain containing a coordinated metal-ion, or another poligalacturonat-chain containing a coordinated metal-ion, or another poligalacturonat-chain C(=O)-, or the residue of the CH- group carrying alcohol OH of galacturonat units), Halogenidion, hydroxideidion or other, biologically acceptable mono-, or bidendate anion, preferably sulphate, carbonate, hydrogen-carbonate, acetate, lactate, malate, citrate, tartarate. #CMT#USE : #/CMT# None given.</p> |
