一般描述
蛋黄中的卵黄高磷蛋白是富含聚阴离子磷酸丝氨酸的蛋白质。该磷酸糖蛋白包含α-螺旋和β-折叠结构元件，由于磷酸丝氨酸的存在，它们的组织不良。它代表约11%的卵黄蛋白，并且是亲水性的。
应用
蛋黄中的卵黄高磷蛋白已用于：
- 作为对照蛋白固定在芯片上用于深紫色蛋白染色，用于监测翻译后修饰
- 作为体外酪蛋白激酶测定中酪蛋白激酶Iε的底物
- 作为凝胶过滤色谱（GFC）和十二烷基硫酸钠-聚丙烯酰胺凝胶电泳（SDS-PAGE）中的标准品，用于定量测定蛋黄提取物中的卵黄高磷蛋白
- 用于逐层（LbL）固定化，用于傅里叶变换红外光谱衰减全反射（FTIR-ATR）研究
生化/生理作用
蛋黄中的卵黄高磷蛋白是一种钙螯合剂，可与蛋黄中存在的铁结合。金属结合功能被用于矿物结合生物活性肽的生产中。它是一种营养保健品，具有磷酸肽生产的潜力。
通过在食物中添加蛋黄喂养大鼠的卵黄高磷蛋白导致镁、铁和钙的吸收减少，但磷的吸收没有减少。
其他说明
含8-10%磷的磷蛋白。 摩尔N/P比约为2.7。

Phosphopeptides are among the most interesting biomolecules with characteristic molecular structure and functions. They usually contain clusters of phosphoserines, which can effectively bind calcium and iron, and inhibit formation of insoluble calcium phosphates or iron complexes. Therefore, phosphopeptides can increase
