Chemical characterisation of each RGTA polymer is detailed in materials and methods.

*ds, degree of substitution of an individual group in one glucosidic unit (SD of ds values were less than 5%, with n = 3).

†CM, CH₂COONa; ‡Su, SO₃Na; §CMB, CH₂CONHCH₂C₆H₅; ¶H, non-reacted hydroxyl groups; **C₃+C₄, global substitution at the C₃+C₄ positions calculated for each group as the difference between the total ds value and the ds value at the C₂ position.
