Kinetic Characteristics of Crystallization in a Model Synovial Fluid Solution in the Presence of Organic Impurities

The kinetic regularities of crystallization (its order and constants) in a model solution of human synovia (inorganic composition) under conditions close to physiological have been investigated. The crystallization constants in a pure solution and in the presence of organic synovia additives with variation in their concentration and supersaturation of the model solution are determined. The following descending order sequence is proposed for the influence of additives on the general and particular kinetic characteristics of crystallization in a model synovial solution: glucose → proline → alanine → glycine → citric acid. It is found that impurities affect to a greater extent the nucleation process rather than growth stages.
