The semipermeable membranes required to produce the fluid flow that
characterizes osmotic phenomena initially came from biological sources; French scientist René Dutrochet wrote in 1828, «it appears from these new studies that the endosmotic and exosmotic phenomena, which I discovered, belong to a new class of physical phenomena, whose powerful intervention in the vital phenomenon is no longer doubtful.»
Congenital sucrase - isomaltase deficiency, a rare inherited metabolic disorder
characterized by the absence or inactivity of the sucrase - isomaltase complex, results in
osmotic diarrhea when sucrose is ingested because it can not be hydrolyzed.
