Abstract
Four calcium compounds containing uronic acids (d(+)-galacturonic and d(+)-glucuronic) in L:M ratio = 2 and 3 were isolated by applying novel (except for one complex) synthetic procedures. The compounds were characterized by elemental analysis, spectroscopic methods (diffuse reflectance and absorption UV-visible, IR, FIR), mass spectrometry, fast atom bombardment (FAB), thermal decomposition, thermogravimetry/derivative thermogravimetry (TG/DTG) data and differential scanning calorimetric studies (DSC). Two modes of water binding in the complexes, i.e., hydration and coordination-like, were established. Computer-aided analysis has shown that further investigations are needed in order to determine the applicability of calcium uronates as calcium carriers.
