Peripheral Assimilation of Fructose in Man.

Abstract
In order to determine the ability of peripheral tissues to assimilate fructose, successive peripheral arterio-venous fructose differences were measured in human subjects during intraven. admn. of fructose solns. First a priming dose was given rapidly and then constant fructose infusion begun. Arteriovenous fructose differences of the order of 11 mg. % were maintained for prolonged periods (160 min.) in the presence of constant arterial (capillary) fructose levels of the order 67 mg. %. Findings were interpreted as evidence for direct assimilation of fructose by peripheral tissues.
