Application

α-Casein from bovine milk is an Immunoglobulin E (IgE)-binding epitope belonging to the Casein phosphoprotein family. It has been used in studies of children with insulin-dependent diabetes mellitus (IDDM), due to the strong cross-reactivity of α-casein antibodies with insulin. Studies of children displaying (IDDM) show higher levels of α-casein antibodies than control siblings, which may serve as a risk marker for IDDM.

Biochem/physiol Actions

Clusters of phosphoserine in casein chelate iron and reduce its bioavailability. Partial enzymatic digestion of casein unmasks phosphorylated residues to alkaline phosphatase, permitting dephosphorylation and increasing the bioavailability of iron.

Preparation Note

Enzymatically prepared from C6780.

Analysis Note

At least 80% dephosphorylated.
