酶的原理是什么

酶作用原理

1.趨近效應(approximation)和定向效應(oientation)酶可以將它的底物結(jié)合在它的活性部位由于化學反應速度與反應物濃度成正比,若在反應系統(tǒng)的某一局部區(qū)域,底物濃度增高,則反應速度也隨之提高,此外,酶與底物間的靠近具有一定的取向,這樣反應物分子才被作用,大大增加了ES復合物進入活化狀態(tài)的機率。

2.張力作用(distortionorstrain)

底物的結(jié)合可誘導酶分子構(gòu)象發(fā)生變化,比底物大得多的酶分子的三、四級結(jié)構(gòu)的變化,也可對底物產(chǎn)生張力作用,使底物扭曲,促進ES進入活性狀態(tài)。

3.酸堿催化作用(acid-basecatalysis)

酶的活性中心具有某些氨基酸殘基的R基團,這些基團往往是良好的質(zhì)子供體或受體,在水溶液中這些廣義的酸性基團或廣義的堿性基團對許多化學反應是有力的催化劑。

4.共價催化作用(covalentcatalysis)

某些酶能與底物形成極不穩(wěn)定的、共價結(jié)合的ES復合物,這些復合物比無酶存在時更容易進行化學反應。

例如:無酶催化的反應 RX+H2O→ROH+Hx慢

有酶存在時 RX+E桹H→ROH+EX快

EX+H2O→E桹H+HX快

酶的原理是什么

酶就是起催化作用.和化學里的催化劑是一樣的道理.它本身不參與反應,反應前后其本身沒有任何變化.生物酶有,蛋白質(zhì)類、固醇類、RNA類!
