應用

β-胡萝卜素已用于:
  • 用作标准品,用于通过HPLC分析对β-胡萝卜素进行定量
  • 用作标准品,用于类胡萝卜素基团真实标准品的鉴定和定量
  • 测定β-胡萝卜素生产时标准曲线的制备
  • 营养测定中的标准曲线制备

生化/生理作用

β-胡萝卜素(维生素原A)是类胡萝卜素的成员之一。这种抗氧化剂在人类生理中起着至关重要的作用。β-胡萝卜素是一种丰富的类胡萝卜素。它被认为是维生素A的前体,维生素A是具有维生素E特性的一种脂溶性抗氧化剂。
维生素原 A,即 β-胡萝卜素能分类作为抗氧化剂的最重要的原因就是它可以在体外抑制自由基引发的过氧化。然而,它在体内究竟表现为抗氧化剂或是促氧化剂却取决于细胞环境。它可以降低许多癌症的发病率,却会增加吸烟者患肺癌的几率。
