产品介绍
α-乳白蛋白(α-LA)已用作标准品研究不同单体蛋白在氨基酸作用下的蛋白表面分配行为研究α-LA与组织蛋白酶D之间的相互作用研究母乳组分对结肠癌细胞系外源性铁元素经上皮通量的增强作用应用: α-乳清蛋白(α-LA)是一种小的酸性乳清蛋白,约占人乳总蛋白质的22%。它是由乳腺上皮细胞产生的。α-LA由两个结构域组成:一个大的α-螺旋结构域和一个小的β-薄片结构域。 α-Lactalbumin (α-LA) is a small, acidic, whey protein that constitutes about 22% of the total proteins in human milk. It is produced by the epithelial cells of the mammary gland. α-LA is made up of two domains, a large α-helical domain, and a small β-sheet domain. Application: α-Lactalbumin (α-LA) has been used as a standard to study the partitioning behavior of different monomeric proteins with exposure to amino acids on the protein surface to study the interaction between α-LA and cathepsin D to study the ability of breast milk fractions to enhance the transepithelial flux of extrinsic iron in colon carcinoma cell line
生化机理
α-乳清蛋白(α-LA)在乳腺内与乳糖合成酶形成络合物,在乳汁生产和调节乳汁量中起作用。它是生物活性肽和必需氨基酸的重要来源,如赖氨酸、色氨酸、支链氨基酸和含硫氨基酸,是婴儿的关键营养。此外,α-LA具有广泛的应用,包括作为促进胃肠道健康和调节睡眠和抑郁的补充剂。α-La还显示出对肌肉减少症、癫痫、情绪障碍和癌症的治疗效果。 它有一个Ca2+Ca 2+ 结合位点,可与Na + 、K + 、Mg 2+ 和Mn 2+ 结合,还有许多Zn 2+ 结合位点。其可通过改变半乳糖基转移酶的底物特异性以增加乳糖形成的速率;半乳糖基转移酶和α-乳白蛋白的复合物称为乳糖合酶。α-乳白蛋白与油酸的复合物显示出与单独的α-乳白蛋白完全不同的活性,对肿瘤细胞具有强烈的细胞毒性。 该复合物称为HAMLET(对肿瘤细胞具有致死性的人α-乳白蛋白)。
