[Characteristics of pantothenic acid transport in membrane vesicles of the brush border of small intestine epithelial cells in rats].
A microfiltration method was used to study the mechanism of pantothenic acid transport in the membrane vesicles of the rat small intestine brush margin. The vitamin uptake proceeded to inner space of the vesicles and was enhanced in presence of sodium ions. The findings suggest that the vitamin transport across the membrane of the small intestine brush margin is mediated by a carrier and proceeds via a Na(+)-co-transport mechanism.
