Opis

Opis ogólny

Casein from bovine milk is a phosphoprotein and forms three-dimensional colloidal supramolecular micelles.[1] 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.[2] Casein is proposed to be the main protective constituent in milk. Casein is an amphiphilic protein.[3]

Zastosowanie

Casein from bovine milk has been used:

• as a solid food sample in the in vivo and the in vitro digestion experiments using rodents[3]
• to prepare P407-casein hydrogels and to study the mechanical effects of the addition of casein to P407[4]
• 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[5]

Działania biochem./fizjol.

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.[6] It can serve as an indispensable diet for rodents.[3]

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.

Jakość

Essentially vitamin free.
