    185 amino acids
    Molecular mass:
    21671 Da
    Quaternary structure:
    • Heteromultimers of alpha-s1 casein and kappa-casein; disulfide-linked
    • In milk, the alpha s1- and beta-caseins precipitate in presence of calcium (so-called calcium-sensitive caseins). Kappa-casein prevents the precipitation of the other caseins by calcium through the formation of large stable colloidal particles termed micelles
