一般說明

氰钴胺(B12)是一种水溶性维生素,通常称为钴胺素。乳制品、肉和蛋是这种维生素的主要来源。

應用

维生素B12已用于:
  • 用作Erdschreiber′s培养基组分
  • 用作杜氏改良Eagle′s培养基的补充剂,用于从新生和成年大鼠中分离出的心室肌细胞
  • 雄性鹌鹑口服用药,用于研究其在减少亚硒酸钠中毒体内负面影响方面的作用。
  • 作为人成肌细胞分化用DMEM培养基/199 (M199)的补充剂。

生化/生理作用

维生素B12代谢为其甲基钴胺素活性形式。恶性贫血患者体内可观测到维生素B12吸收受阻。维生素B12对成红细胞发育至关重要。妊娠会导致维生素B12水平下降。衰老会到维生素B12吸收减少。它可充当脂肪、碳水化合物和蛋白质代谢中的辅酶。它是细胞生长、遗传稳定性和体外存活必需的成分。参与支持一碳代谢。存在于许多经典和无血清配方中。
