the procedure involves initial enzymatic hydrolysis , by which the amino acid moieties are removed from the glycine and taurine conjugated bile acids by means of choloylglycine hydrolase , followed by thin-layer chromatographic separation of the unconjugated bile acids , cholic acid , chenodeoxycholic acid , and deoxycholic acid .
