Do taste receptors respond to perturbation of water structure?
The pmr spin-spin pulse relaxation times (T2 values) of the L-amino acids are examined in relation to their taste threshold values. There is an inverse trend between T2 value and threshold value with a good correlation for amino acids whose natural pH is close to neutrality. These results may indicate that taste receptors respond to perturbation of water structure.
