Analysis Note:	Essentially vitamin free.
Application:	Casein from bovine milk has been used: • as a solid food sample in the in vivo and the in vitro digestion experiments using rodents • to prepare P407-casein hydrogels and to study the mechanical effects of the addition of casein to P407 • in the preincubation solution, to increase the photostability of the quantum dots and to decrease nonspecific binding, for real-time imaging of single synaptic vesicles in hippocampal neurons
Application:	Casein from bovine milk is a phosphoprotein. There are four main types of Casein which make up approximately 80% of the total protein in bovine milk: α-s1 Casein, α-s2 Casein, β-Casein, and κ-Casein. Casein is proposed to be the main protective constituent in milk.
Biochem/physiol Actions:	Casein is useful in food industries and non-food applications. It has the property for emulsification, foam formation, and stabilization, water-binding, and gelation. Casein is also considered heat and acid stable. It can serve as an indispensable diet for rodents.
Biochem/physiol Actions:	Partial gastrointestinal digestion of casein is a rich source of bioactive peptides, such as β-casomorphin. However, bovine casein is not homogeneous; variants A1 and B do lead to production of β-casomorphin 7 production, while A2 does not.
General description:	Casein from bovine milk is a phosphoprotein and forms three-dimensional colloidal supramolecular micelles. There are four main types of casein which make up approximately 80% of the total protein in bovine milk: α-s1 casein, α-s2 casein, β-casein, and κ-casein. Casein is proposed to be the main protective constituent in milk. Casein is an amphiphilic protein.
