At a 2.0 mM concentration, D-mannoheptulose hexaacetate, but not unesterified D-mannoheptulose, inhibited the generation of radioactive acidic metabolites by rat erythrocytes exposed to D-[U-¹⁴C]glucose (8.3 mM). It is proposed that D-mannoheptulose hexaacetate represents a valuable tool to interfere with the phosphorylation of D-glucose in cell types otherwise resistant to the heptose.
