一般描述

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.

应用

来自牛奶的酪蛋白是一种磷蛋白。酪蛋白有四种主要类型，占牛奶中总蛋白质的约80％：α-s1 酪蛋白、α-s2 酪蛋白、β-酪蛋白和κ-酪蛋白。酪蛋白被认为是牛奶中的主要保护成分。
Casein from bovine milk has been used:

• as a solid food sample in thein vivoand thein vitrodigestion 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

生化/生理作用

部分消化的酪蛋白是生物活性肽的丰富来源，如β-酪啡肽。然而，牛酪蛋白是不同质的；A1和B变异的确会导致产生β-酪啡肽7，但A2却不会。
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.
