摘　　要：乳蛋白的氨基酸(AA)含量和比例比较理想,是一种营养价值很高的蛋白质。除小部分来源于血液外,乳中绝大部分的蛋白质由乳腺上皮细胞利用血液中的氨基酸或小肽从头合成。乳中的蛋白质含量和组成直接影响乳蛋白的营养和生理特性以及乳制品的产量。只有清楚地了解乳蛋白合成的调控机制,才能更好地通过营养策略来提高乳蛋白含量。因此,对奶牛乳腺细胞内乳蛋白的合成调控进行了简要综述。Because the ideal amino acid content and composition,nutritional value of milk protein is very high.In addition to a small part from the blood,most of the protein in milk are synthesized in the mammary epithelial cells using amino acid or small peptide from the blood.Content and composition of milk protein will affect the milk nutritional and physiological characteristics and dairy production. Better understand the regulation mechanism of milk protein synthesis could help us to raise the protein content in milk by nutrition strategies.Therefore,the regulation of milk protein synthesis in bovine mammary epithelial cells is reviewed.
