Kinetic characteristics of crystallization in prototypes of human blood plasma

Abstract

This paper presents the results of studies on the kinetics of nucleation and growth process of crystals in solutions simulating the composition of human blood plasma. By using optical density, conductivity and pH ranges of the identified properties of the system that simulates the blood plasma, depending on the supersaturation: 3–15, 15–30, 30–90. The order and the constant nucleation (n = 1.6; k = 88.61) calcium phosphate forming in model solution of blood plasma. A comparison of model types crystallization solutions for plasma systems with different initial supersaturation. And the presence of octocalciumphospate calcium- deficient hydroxyapatite in the composition of the sediment was found. It was found that when the supersaturation changes the composition of the precipitate — calcium octophosphate in converted into hydroxyapatite. The influence of some inorganic (magnesium ions) and organic (alanine and glucose) additives on the crystallization kinetics of human plasma prototype was shown.
