‘That is, regardless of the tautomeric form in which the molecule finds itself there is always conserved an aromatic core to which is attached a hydroxyl group peri to a carbonyl group.’
‘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.’
‘All these techniques pointed to the fact that the unstable form has the 7,14-diketo tautomeric structure, like the stable form, and not the 1,6-diketo structure.’
‘Although the double bond in the 7-membered ring of hypocrellin B constrains it to exist in one conformational and tautomeric form, it appears that in the excited state this is not the case.’
