一般說明

β-来自酪蛋白牛乳，是免疫球蛋白E（IgE）结合表位，属于分泌性钙结合磷蛋白家族。它由209个氨基酸和五个磷酸基团组成。β-酪蛋白在C-末端具有球状疏水结构域，在N末端和脯氨酸残基具有高度溶剂化和带电荷的结构域。

應用

β-酪蛋白来自牛乳，已用作蛋白水解测定中的蛋白底物。它还已用于将聚丙烯酰胺凝胶嵌入β-酪蛋白酶谱中。
它已被研究作为生物活性肽，例如鸦片制剂、免疫刺激剂、抗细菌剂和肽酶抑制剂，的产生剂。

生化／生理作用

酪蛋白（主要乳蛋白）的多态性部分。A1和B（不是A2）异构体在胃肠道蛋白水解消化过程中可产生生物活性肽，β-酪啡肽，其对人类健康具有广泛的影响。为了避免这种可能性，一些研究人员正在尝试选择含有A2异构体的奶牛。
