title: [Intestinal transport of cycloleucine (author's transl)].
abstract: Cycloleucine transport across the epithelial cells of the turtle intestine has been studied. It was assumed that the epithelium constituted a single homogeneous compartment. The results obtained by tracer techniques show that the epithelium, in transport, comprises more than one compartment, a separate one, at least, for intestinal absorption and secretion processes. This heterogeneous character makes impossible to attribute a tissue concentration to the epithelium as a whole, so that the existence of an aminoacid accumulation cannot be affirmed.
