General description

Casein is a calcium phosphate-binding protein that constitutes up to 80% of the total milk proteins. In bovine milk, it exists in four types such as αS1, αS2, β, and κ. Casein can adapt its structure according to the changes in the environment and assemble in colloidal structures to form casein micelles. Casein micelles constitute about 10% of the volume in skim milk.
