Since early last century , abundant research has addressed the link between sweetness and the structure of sweeteners. A unified explanation of Shallenberger and Acree's states that the sweetener is bound to the sweet receptor by the “glucophore” formed by a proton donor (AH) and an acceptor (B). The conformational behavior of the natural sweeteners, ketohexoses, has been revealed in a supersonic expansion by Fourier transform microwave spectroscopy coupled with a laser ablation source. From the detailed structural information extracted from these experiments, a singular structural signature in the short H‐bond network OH (2) ⋅⋅⋅OH (1) ⋅⋅⋅O ring that might be correlated to their sweetness, has been characterized in their most abundant species. More information can be found in the Full Paper by J. L. Alonso et al. on page 16829 ff.
