[Active transport of pantothenic acid in the small intestine of the rat].

Pantotheric acid transport non-linear dependence was found in vivo and in vitro tests in the rat small intestine. Kinetic constants of the above process were determined. Dinitrophenol, sodium fluoride, anoxia, 4-phosphopantothenate and pantoilaminocaproic acid inhibited vitamin transfer against concentration gradient. Dependence of pantothenate transport rate upon sodium concentration was revealed.
