Study of acid-base properties of bilirubin derivatives using capillary zone electrophoresis
Kupcová, Kristýna ; Jelínek, Ivan (advisor) ; Martínková, Markéta (referee)
in English The concise summary of literary information about bilirubin and its structure derivative ranarubin is the topic of this thesis. The experimental part is dedicated to investigation of some properties of this substances and their comparison. The rate of degradation and acid- base behaviour was monitored under the laboratory conditions using capillary zone electrophoresis. The results point to differences in their behaviour.
Bilrubin - physicochemical properties and biochemical importance
Kupcová, Kristýna ; Hudeček, Jiří (advisor) ; Martínková, Markéta (referee)
This thesis briefly summarizes the literary data concerning bilirubin. In addititon to this, its experimental part is devoted to comparison of stability of bilirubin and its derivative, ranarubin, towards photolysis in aerobic conditions. The photolytic experiments were carried out at wavelength 366 nm for 4 hours. The resulting photolysates were characterised by absorption spectroscopy (400 - 800 nm) and mass spectrometry. The data obtained show a high degree of similarity for both compounds, which are both relatively stable against photolytic splitting and photooxidation to biliverdin.
