自19世纪末德国生物学家毕希纳证明酵母无细胞提取液能使糖发酵产生酒精,第一次提出酶的名称以来,人类已经发现并鉴定出3000多酶。酶作为一种催化剂,已被广泛地应用于轻工业的各个生产领域。近几十年来,随着酶工程的迅猛发展,酶在生物工程、生物传感器、环保、医药等方面的应用也日益扩大,可以说酶已成为国民经济中不可缺少的一部分,现实生活中,人们的衣、食、住、行及其他方面的新技术几乎都离不开酶。
一些人工合成的手性配体或催化剂被称为化学酶(Chemzyme),它们的催化作用类似于酶的催化作用具有很高的对映选择性和效率。手性1,3,2-恶唑硼烷就是一类重要的化学酶。

脉冲可以在大脑中产生电流从而刺激神经元释放更多的情绪改善化学酶,例如血清素,多巴胺以及降肾上腺素。
The pulses generate an electric current in the brain that stimulates neurons to increase the release of more mood-enhancing chemicals like serotonin, dopamine and norepinephrine.
So, that's kinetics -- how fast a reaction will go, and from the perspective of someone who's a biochemist, I'm interested in kinetics and enzyme kinetics, and thinking about molecules that catalyze reactions in the body.
所以这就是动力学,一个反应发生的有多快,从一个生物化学家的角度,我喜欢研究动力学,酶动力学。
Restriction enzymes are just a kind of enzyme, enzymes are protein molecules that make a chemical reaction go faster, and the chemical reaction that restriction enzymes do is cutting DNA.
限制性内切酶是一种酶,而酶是加速化学反应的蛋白质分子,限制性内切酶加速的化学反应,是切割DNA
Synthesis always occurs in one direction and that makes sense to you now because you know there's a directionality and the chemistry is different going one way than the other and this DNA polymerase only works on the chemistry going in one direction.
NA复制过程是单向的,现在你们该明白原因了,因为DNA单链有方向性,DNA在两个方向上化学性质不同,DNA聚合酶,只在一个方向上起作用
