摘要：

beta-casein, a self-associating protein, has been extensively studied over the years, and it is a molecule that is of academic, industrial, and clinical relevance. Therefore it is of interest to understand the structural and conformational properties of the assemblies, also denoted micelles. Here we show that beta-casein possess a polydisperse distribution of equilibrium micelles, which has, to the authors knowledge, not been published before. (C) 2017 Elsevier Ltd. All rights reserved.
