Abstract/OtherAbstract:
Bile acids (BAs) are a family of natural steroids biosynthesized from cholesterol in the liver that tend to form aggregates in solution. A fluorescent derivative of cholic acid, namely 3-Dns-ChA, was employed as a reporter to establish the speciation diagrams of the most abundant BAs that can be found mainly in three microenvironments, solution, primary and secondary aggregates. The developed methodology is based on the analysis of the combined steady-state and time-resolved experiments performed on 3-Dns-ChA whose emission behavior was found to be strongly medium dependent. In particular, speciation diagrams of sodium glycocholate (NaGCh), sodium taurocholate (NaTCh), sodium chenodeoxycholate (NaCDCh), sodium glycochenodeoxycholate (NaGCDCh), sodium deoxycholate (NaDCh) and sodium ursodeoxycholate (NaUDCh) were successfully built up.
