Bile salts of frogs: a new higher bile acid, 3 alpha, 7 alpha, 12 alpha, 26-tetrahydroxy-5 beta-cholestanoic acid from the bile Rana plancyi.
Bile salts of ten species of frogs of the family Ranidae were examined by means of thin-layer chromatography, gas-liquid chromatography, and gas-liquid chromatography-mass spectrometry. Their major bile alcohols were ranol, cyprinol, or bufol. Four species of frogs contained lesser amounts of higher bile acids, and in two species C24 bile acids were present. A higher bile acid that has not been...
متن کاملThe comparison of alpha power, peak alpha frequency, frontal alpha asymmetry between irritable bowel syndrome and healthy people
Irritable bowel syndrome (IBS) is a chronic functional gastrointestinal disorder that is characterized by abdominal pain or discomfort and changed intestinal habits. The aim of This study was the comparison of features of brain oscillations in alpha frequency band by using rest-electroencephalography (EEG) between patients with IBS and healthy control. 11 IBS patients (7 female and 4 male) and ...
متن کاملEnzymatic determination of bile acids from liver cells with 3 alpha-hydroxysteroid dehydrogenase--a warning.
3 alpha-Hydroxysteroid dehydrogenase was used to monitor bile acid production by rat hepatocyte suspensions. Several observations suggested that the method lacked specificity and detected some other metabolites besides bile acids. This was due to a malate dehydrogenase activity present in four different commercial enzyme preparations of 3 alpha-hydroxysteroid dehydrogenase. It is concluded that...
متن کاملBioluminescence measurement of primary bile acids using immobilized 7 alpha-hydroxysteroid dehydrogenase: application to serum bile acids.
A simple, rapid, and sensitive bioluminescence method for measuring primary bile acids has been developed and validated. The method is based on enzymatic dehydrogenation of bile acids using a bacterial 7 alpha-hydroxysteroid dehydrogenase that is co-immobilized on Sepharose 4B beads with NADH:FMN oxidoreductase and a bacterial luciferase. The assay is specific for 7 alpha-hydroxy bile acids and...
متن کاملEpimerization of the 7-hydroxy group of bile acids by the combination of two kinds of microorganisms with 7 alpha- and 7 beta-hydroxysteroid dehydrogenase activity, respectively.
An unidentified gram-positive anaeroic organism capable of dehydrogenating the 7 beta-hydroxy group of ursodeoxycholic acid was recovered from human feces. By combined action of this organism with the ordinary 7 alpha-dehydrogenating bacteria, chenodeoxycholic acid and cholic acid alike were readily converted into their respective 7 beta-epimers and the reverse reactions were also carried out. ...
