Web5 okt. 2024 · Theory of helix-coil transitions in biopolymers by Douglas Poland, 1970, Academic Press edition, in English Theory of helix-coil transitions in biopolymers (1970 … Helix-coil transition models assume that polypeptides are linear chains composed of interconnected segments. Further, models group these sections into two broad categories: coils, random conglomerations of disparate unbound pieces, are represented by the letter 'C', and helices, ordered states where the chain has assumed a structure stabilized by hydrogen bonding, are represented by the letter 'H'.

Web31 jan. 2002 · In Ref. it is shown that the higher temperature T 1 = 480 K marks the helix-coil transition, i.e. the temperature where secondary structure elements (α-helices) are formed. At the lower temperature T 2 = 260 K, the peptide then folds into its native structure, a U-turn-like bundle of two (antiparallel) α-helices connected by a turn. Web11 apr. 2024 · More useful parameters are discussed, including protein cooperativity. The new parameters are embedded in a well-defined thermodynamic context and are amenable to molecular dynamics calculations.
