The Mechanism of Precipitation of Biological Minerals. The Phosphates, Oxalates and Carbonates of Calcium*
The precipitation of the phosphates, oxalates, and carbonates of calcium is complicated by the possible formation of different precursor phases involving polymorphs, hydrates, and acid salts. In order to elucidate the mechanisms of the reactions, it is necessary to study the kinetics under conditions of controlled supersaturation calculated from the activities of free ionic species. In general,...
متن کاملCasein precipitation equilibria in the presence of calcium ions and phosphates
Calcium ion induced aggregation and precipitation equilibria of b-casein were studied in the presence or absence of monoand polyphosphates at pH 5.5 and 7.5. We analyze the data by assuming ion binding at a well-defined stoichiometric ratio, leading to protein charge neutralization and formation of slightly soluble complexes. The precipitation curves are in good agreement with the model, showin...
متن کاملEffects of LDL, cholesterol, and their oxidized forms on the precipitation kinetics of calcium phosphates.
BACKGROUND LDL, cholesterol, and their oxidized forms are known cardiovascular risk factors and are often found in atherosclerotic lesions of various stages. Little is known, however, about whether they are directly involved in the formation of calcium phosphate compounds. METHODS We used the pH-stat technique to follow the kinetics of calcium phosphate precipitation at pH 7.4, 37 degrees C, ...
متن کاملElectrocrystallization of Calcium Phosphates
The interest in electrocrystallization of calcium phosphates (CaP) in general, and of hydroxyapatite (HAp) specifically, results from the promising industrial benefits, unique microstructures, and properties of the deposits produced by this process, and the possible similarity to bone mineralization in vivo. In this paper, our work on electrocrystallization of HAp and octacalcium phosphate (OCP...
متن کاملSolubility of calcium phosphates.
Solubil ity is one of the most important properties of calcium phosphate salts. It is the solubil ity that determines the direction of many reactions that involve calcium phosphates such as dissolution, precipitation, hydrolysis, and phase transformation. Calcium phosphate solubil ity also plays a maior role in biological processes that involve formation and resorption ol' hard tissues as well ...
