Application

来自牛奶的酪蛋白已用于：
  • 免疫化学中的阻断剂
  • 一种底物，以确定解聚素和角鲨毒液中的催化活性
  • 作为澄清剂，测试其对白葡萄酒蛋白质稳定性的影响

牛奶中的酪蛋白是一种磷蛋白。酪蛋白主要有四种类型，约占牛奶总蛋白的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主要的保护成分

Biochem/physiol Actions

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。
酪蛋白因乳化、起泡、凝胶化、持水能力以及通过官能团与生物活性分子相互作用等特性，被应用于营养食品和各种配方，如水凝胶、薄膜、纳米胶束和纳米颗粒。这种蛋白质很容易获得，可以保护药物不被酶降解，而且无毒，因此酪蛋白有可能用于口服给药系统。

General description

来自牛奶的酪蛋白是一种磷蛋白。酪蛋白有四种主要类型，约占牛奶总蛋白质的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，由于具有天然的生物相容性和生物可降解性，被公认是安全的（GRAS）。

Other Notes

本产品为技术级酪蛋白。与部分纯化酪蛋白产品相比，技术级酪蛋白蛋白杂质含量更高，脂肪含量更高。
