A coarse-grained molecular model of amyloid fibrils systems

We report a computational model for amyloid fibrils and discuss its main features and ability to match different experimental morphological characteristics. The model captures the liquid crystalline and cholesteric behaviours in short and rigid amyloid fibrils and shows promising extendibility to mo...

Description
Summary:We report a computational model for amyloid fibrils and discuss its main features and ability to match different experimental morphological characteristics. The model captures the liquid crystalline and cholesteric behaviours in short and rigid amyloid fibrils and shows promising extendibility to more complex colloidal liquid crystals. This work presents molecular model identification for macroscopic chirality emergence in amyloid fibrils. The data driven model captures the cholesteric phase behaviour of amyloid fibrils, and it is extendible to other colloidal liquid crystals.
