应用
- β-胡萝卜素已被用作利用HPLC（高效液相色谱法）测定血浆样品中β-胡萝卜素水平过程中的标准品。
- 它已被用于研究维生素对放射性培养中分枝杆菌生长的影响。
- 它已被用作 果蝇（Drosophila melanogaster） 生长培养基中的补充剂，以利于维生素A的摄入。
生化/生理作用
最重要的维生素原 A。
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。
注意
最低购买数量。 开启后一个月需丢弃。

Mixtures of neutral lipids containing cholesteryl esters and beta-carotene were used to reconstitute the lipid core of heptane-extracted low-density lipoproteins (LDL). The resulting preparations of reconstituted LDL, referred to as r-[cholesteryl ester + beta-carotene]LDL, exhibited temperature-dependent circular dichroism (CD) in
