Hi,

Please would you update the structural data of polynyl alcohol CHEBI:17246 with the attached mol file and create the corresponding structure for CHEBI:16571, the oxidized polyvinyl alcohol

Thanks

Anne

Hi Anne,

The structure suggested here is not correct. The polymer would be terminated at both ends by ethylene glycol groups (not correct) and also the polymer suggested here would have an odd number of carbons. Given that the monomer, vinyl alcohol, has 2 carbons, any polymer derived from it must have an even number of carbons. Therefore I am unable to amend the structure.

Cheers, Steve

Hi Steve,

You're right, I made a mistake with the proposed structure for CHEBI:17246. I have corrected the structure and attached an updated version of the molfile. Sorry for the mistake and thanks for your help

Cheers, Anne
