3,4苯并芘(Benzo(a)pyrene)是一个环境化学致癌物,从工厂或车辆排出的废气中含有大量的3,4苯并芘,家庭中煤的燃烧以及吸烟,都有此种致痛物排入空气中。(Benzo(a)pyrene)又简称B(a)p或Bp,具有肯定的致癌作用,可因与之接触的方式不同而引起不同部位的癌瘤。但其致癌作用不是由其本身引起的,而是由于Bp在体内的代谢生成代谢产物,它们可与细胞中的DNA,RNA或蛋白质相作用,而导致细胞的癌变。Bp的这种活化,由依赖于细胞色素p-450的混
3,4 Benzo (a) pyrene is an environmental chemical carcinogen, which contains a large amount of 3,4-benzopyrene in the exhaust gas discharged from a factory or a vehicle, and is burned and smoked by households Pain caused by discharge into the air. (Benzo (a) pyrene), also known as B (a) p or Bp, has a positive carcinogenic effect and may cause cancer of different parts due to different ways of contact with Benzo (a) pyrene. However, its carcinogenicity is not caused by itself, but due to Bp metabolism in the body to produce metabolites, which can interact with DNA, RNA or protein in cells, resulting in canceration of cells. This activation of Bp consists of a combination of cytochrome p-450 dependent
