Effects of sodium on solute transport between compartments in intestinal mucosal epithelium

Abstract

THE uptake of amino acids and of some monosaccharides into the intestinal mucosal cell across the brush-border membranes requires sodium in the intestinal lumen1–3. An hypothesis of the existence in brush-border membranes of systems for transport that depend on Na—for example, the ‘Na gradient’ hypothesis4—although necessary, is not sufficient to account… (More)
