Abstract
AbstractElectrophoresis and titration experiments on amylose solutions and gels are described. The experimental results clearly demonstrate the negative charge of the amylose molecules at pH values of 11 and higher. With the assumption that a monomer unit can carry one charge only, pK's of amylose are calculated. The agreement between the pK's of amylose and glucose forms an indication that hydroxyl groups dissociate in the above‐mentioned pH range.
