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。

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.
