## Abstract Using 5 samples of well‐purified Na‐gellans (Na‐gellans G1–G5, weight‐average molar mass __M__~w~ = 120 × 10^3^−32 × 10^3^ at 40°C), the effects of molar mass on the coil‐to‐double‐helix transition in aqueous solutions with 25 mM NaCl were studied by light scattering and circular dichro
