英文名称 | Natrual β-Carotene |
生化机理 | β-Carotene (pro-vitamin A) is a member of carotenoids. This antioxidant plays a vital role in human physiology. β-Carotene is an abundant carotenoid. It is considered as a precursor of vitamin A, which is a lipid soluble antioxidant with vitamin E properties. The most important of the provitamins A, β-carotene can be classified as an antioxidant due to its inhibition of radical initiated peroxidation in vitro. However, in vivo it appears to act either as an antioxidant or a prooxidant depending on cellular environment. It reduces the incidence of many cancers, but enhances lung cancer incidence in smokers. |
