Abstract The concentrations of carbon‐13 in the individual carbon atoms of 3‐hydroxy‐2‐butanone (acetoin) from apple cider vinegar decrease with decreasing oxidation level in the sequence. Because the distributions of isotopes within biological compounds are controlled by kinetic and equilibrium effects, intramolecular isotopic analyses may provide a means of defining the equilibria between metabolic pathways and of recognizing the molecular remnants of pre‐existent organisms in geological samples.
