Glycerol specifically deuterated at C-1, C-2, or C-3 was prepared and used for the biosynthesis of bacterial cellulose with Acetobacter xylinum.The material obtained were converted into glucitol hexaacetate and analyzed by 250-MHz nuclear magnetic resonance and mass spectrometry. The spectra indicated that the protons of the C-3 position of the starting glycerol were incorporated as substituents of the C-6 and C-1 positions of the cellulose. Similarly, protons of the C-2 and C-5 positions of the cellulose came essentially from water and the protons bonded at the C-3 and C-4 positions of the cellulose from protons bonded to C-1 of the starting glycerol.
