## Abstract The helix–coil transition in polypeptides was studied by methods of statistical mechanics, taking account of interaction between “melted” amide groups through hydrogen bonds. The statistical sums are calculated in the explicit form for two limit cases: (1) the dilute solution when the m

## 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
