Abstract
⺠Alginates partially (0-8%) oxidized with periodate. ⺠Degradation in pH-range 3-10.4 studied by SEC-MALLS. ⺠pH dependence shows β-elimination as major degradation mechanism at pH 7.4 and higher. ⺠Activation energy 88 kJ/mol for labile dialdehydes, 113 kJ/mol for unoxidized residues. ⺠Level-off molecular weight caused by resistant dialdehydes. ⺠Rate of degradation in gel state proportional to the degree of oxidation.
