一般描述

氰钴维生素(B12)是一种水溶性维生素,主要存在于乳制品、肉类和蛋类等动物产品中。它属于B12类维生素,通常称为钴胺素。氰钴维生素由四个吡咯环和一个中心钴原子由四个赤道含氮配体配位而成。

应用

氰钴维生素已被用于研究其对预防结肠癌的作用。
细胞体外生长、基因稳定性和生存所必需成分。可支持单碳代谢。存在于许多经典和无血清配方中。

包装

5 g in glass bottle
500 mg in glass bottle

生化/生理作用

氰钴维生素可用于制备多种维生素补充剂和强化食品。其可用作辅酶,在异构酶催化下将L-甲基丙二酰辅酶A转化为琥珀酰辅酶A。氰钴维生素可于治疗维生素B12缺乏症。氰钴维生素符合USP测试规范。
