- Аннотация: Calcium hydrogen phosphate dihydrate and amorphous calcium phosphate have been synthesizedin an aqueous suspension of medium molecular weight chitosan in the presence of glutamic or aspartic acid.Xray diffraction and transmission and scanning electron microscopy characterization showed that the morphology of the phases present depended on the nature of the amino acid. The amino acids participate in theprotonation of the amino groups of the chitosan and, probably, in the formation of chelate intermediate compounds with calcium ions, which act as calcium phosphate nucleation centers.
