  • Point mutations, for example, can be due to tautomeric shift (a movement of hydrogen atoms that changes the properties of bonding).
  • This is corroborated by the fact that the interconversion between A 1 and A 3 is very fast at room temperature, which cannot be explained by a simple tautomeric conversion.

Example sentences
  • This is tautomerism, where two isomers exist in dynamic equilibrium with each other.
  • The same is true of tautomerism in aromatic molecules.
  • As explained earlier, curcumin exists in keto-enol tautomerism; these tautomeric equilibria both in the ground and in the excited states can be influenced by the solvent protons.
