Abstract
Brush border membrane can be isolated as closed vesicles, and transport components of 59Fe2+ and 59Fe3+ uptake by brush border membrane vesicles have been identified. This brush border membrane transport is subject to adaptive regulation in response to varying whole-body iron requirements and accounts quantitatively and qualitatively for in vivo mucosal 59Fe2+ uptake but not 59Fe3+ uptake. Investigation of the mechanism of 59Fe2+ transport by rabbit brush border membrane vesicles has led to the isolation of a membrane Fe2+- binding constituent, identified as non-esterified fatty acid (NEFA).
