UPTAKE OF GLUCOSE ANALOGUES BY RAT BRAIN CORTEX SLICES: Na+‐INDEPENDENT MEMBRANE TRANSPORT

Abstract
Abstract— The glucose analogues 3‐O‐methyl‐D‐glucose and α‐methyl‐D‐glucoside were not metabolized in brain tissue.The uptake of these two sugars into the intracellular compartment of brain cortex slices was investigated using media with normal and low Na+ concentration (replacement of all NaCl with choline Cl). The cellular transport was not Na+‐dependent. The transport mechanism clearly distinguished between the two sugars in both normal and low Na+ media.
