Study of Enantiomers in Pathological Biomineralization.

The study of biominerals of a pathogenic nature in organisms is relevant and necessary for establishing the mechanism of their formation and solving many practical issues. Recently, intensive research has been carried out in the field of biochemistry of D-amino acids, it is believed that they can be potential biomarkers of various pathological processes in the human body. The presence of enantiomers of amino acids and their role in the mechanism of formation of gallstones, the issue has not yet been studied. The paper presents data on the distribution of D-enantiomers of amino acids, their content and ratio with L-forms in the composition of gallstones. A comparative analysis of the obtained results on gallstones with urinary stones is shown. It has been established that there is a relationship between the enantiomers of amino acids and the calcium mineral component. [ABSTRACT FROM AUTHOR]
