摘要

The molecule of β-casein, one of the major milk proteins, is a polypeptide with a charged polar N-terminal region and a practically neutral hydrophobic C-terminal region, so that it exhibits strong amphiphilic properties . The polypeptide chain of the protein contains numerous unstructured regions , which makes β-casein a sufficiently flexible molecule whose peptide and side groups are easily accessible for the solvent. In an aqueous solution, β-casein exhibits the properties of a surfactant and shows a strong tendency to self-association to form spheroidal micelles . Caseins are widely used in food production, often in combination with alcohols .
