Abstract

The role of the extracellular medium in influencing metal uptake
into cells has not been described quantitatively. In a chemicallydefined model system containing albumin, zinc influx into endothelial
cells correlates with the extracellular free zinc concentration. Allosteric
inhibition of zinc-binding to albumin by free fatty acids increased
zinc flux.
