OPTIMIZATION OF TYROSINE DETERMINATION METHOD

Through photocolorimetric research of tyrosine solutions of different concentrations CTyr = 0.2 ÷ 0.5 g /L was verified the possibility of determining the exact concentrations of the amino acid in aqueous solutions by constructing a calibration graph. The conditions of the study (pH of solutions, temperature, time) without the use of aqueous-organic media are clarified. Concentration restrictions for the analysis of tyrosine containing products (plant materials, pharmaceutical products, etc.) are determined.
