Transport systems involved in uptake and biliary secretion of bile salts have been extensively studied in rat liver; however, little is known about these systems in the human liver. In this study, we investigated taurocholate (TC) transport in canalicular and basolateral plasma membrane vesicles isolated from 15 human livers (donor age 6-64 yr). ATP stimulated the uptake ofTC into both canalicu...

Computerized molecular models of adenosine triphosphate, adenosine tri-arsenate and adenosine trivanadate have been generated using the molecular mechanics technique. The analysis of structural parameters indicated that, at least theoretically, adenosine triarsenate is a realistic candidate for replacement of adenosine triphosphate in biochemical pathways. On the contrary, the structural arrang...

The method described here allows the quantitative simultaneous determination of adenosine 5'-triphosphate, adenosine 5'-diphosphate, adenosine 5'-monophosphate, adenosine, guanosine 5'-triphosphate, guanosine 5'-diphosphate, guanosine, inosine 5'-monophosphate, inosine, uric acid, xanthine, hypoxanthine and beta-nicotinamide adenine dinucleotide by ion-pair high performance liquid chromatograph...
