'細(xì)胞色素P450'[1](英語:cytochrome P450)超家族(官方縮寫為CYP)是一大類多種多樣的酶。大多數(shù)細(xì)胞色素P450酶的功能是催化氧化有機(jī)化合物。細(xì)胞色素P450的底物包括有:如脂質(zhì)與甾體激素的代謝中間產(chǎn)物,亦有藥物與其他毒性化學(xué)物質(zhì)等非生物物質(zhì)。細(xì)胞色素P450類是涉及藥物代謝與生物激活作用的主要酶類,約占到各種代謝反應(yīng)總數(shù)的75%。
由細(xì)胞色素P450催化的最常見反應(yīng)就是單加氧酶反應(yīng),例如將氧氣中的一個氧原子插入到有機(jī)底物(以RH表示)中,而另一個氧原子被還原形成水:
