Milk Protein | MilkFactsfo

Milk Protein Physical Properties The caseins in milk form complexes called micelles that are dispersed in the water phase of milk. The casein micelles consist of subunits of the different caseins ( α- s1, α- s2 and ß) held together by calcium phosphate bridges on the inside, surrounded by a layer of 6 -casein which helps to stabilize the micelle in solution.
