Abstract
Slices of rat kidney cortex, on incubation in a saline medium, formed D-glucose from the following substances: D-fructose, D-galactose, D-mannose, L-sorbose, L-arabinose, D-xylose, glycerol, myo-inositol, L-iditol, sorbitol, xylitol, ribitol, methylglyoxal, dihydroxyacetone, L-glyceraldehyde, D-glyceraldehyde, DL-glyceraldehyde, DL-glycerate. Values for the rates of glucose formation from these precursors are given. No glucose was formed from L-rhamnose, D-arabitol, D-arabinose, D-ribose, L-fucose, D-lyxose, mannitol, dulcitol, D-glucuronate, propane-1, 2-diol and propan-2-ol. The pathways of glucose formation from the various precursors are discussed. L-Glyceraldehyde inhibited the formation of glucose from D-glyceraldehyde.
