What are the key thermodynamic parameters that govern amyloid fibril formation?1 answersAmyloid fibril formation is governed by several key thermodynamic parameters. The thermodynamic stability of amyloid fibrils is an important determinant of their lifetimes and processing in vivo. The concentration dependence of chemical depolymerization of amyloid fibrils suggests that cooperative polymerization, which is compatible with the nucleated polymerization process, can quantitatively describe the thermodynamic data. The ionic strength dependence of amyloid fibril stability and growth kinetics provides evidence for the product-like nature of the transition state of amyloid fibril growth. Additionally, equilibrium properties of fibril-like structures made of amyloid proteins can be studied using a two-dimensional coarse-grained model, allowing for the estimation of free energies to dissociate proteins from fibrils and the determination of thermodynamic quantities such as heat capacity and entropy.
