Gastaldi G, Laforenza U, Casirola D, Ferrari G, Tosco M, Rindi G: Energy depletion differently affects membrane transport and intracellular metabolism of riboflavin taken up by isolated rat enterocytes. J Nutr. 1999 Feb;129(2):406-9.
Isolated rat enterocytes, both normal and those de-energized with rotenone, were used to study the energy dependence of membrane and intracellular intestinal riboflavin transport in vitro.
Both membrane and intracellular events were inhibited by unlabeled riboflavin and analogs, which are good substrates for flavokinase, thus demonstrating the paramount role of this enzyme in riboflavin intestinal transport. |
