And it's those protein-breaking enzymes, or proteases, in particular that wreak havoc for your mouth.

特别是那破坏蛋白质的酶，或称蛋白酶，会你的口腔造成严重的破坏。

Trypsins are a type of protease, which is an enzyme that can break down other proteins.

胰蛋白酶是类蛋白酶，能够水解多种蛋白质。

Neutrophils arrive quickly at the scene, and often release superoxide and their own proteases, which contribute to the problem.

中性粒细胞迅速赶来，并释放超氧化物和它们自己的蛋白酶，加剧事态展。

So this antitrypsin protein is a protease inhibitor, and inactivates trypsins, thereby preventing protein breakdown.

而抗胰蛋白酶就是种蛋白酶抑制剂，通过抑制胰蛋白酶防止蛋白质水解。

Professor Terrence said nicotine is connected to high protease levels in the lungs.

特伦斯教授说，尼古丁与肺部的高蛋白酶水平有关。

The best way of describing is the molecular scissors, so proteases are proteins that cut up other proteins.

对这种物质最好的形容就是分子剪刀，蛋白酶是切割其他蛋白质的蛋白质。

Normally, trypsinogen isn't activated until it is cleaved by protease enteropeptidase which is found in the duodenum.

通常情况下，胰蛋白酶原被十二指肠中的肠肽酶切割之后才会被激活。

Last September, the gamers of Foldit solved the three-dimensional structure of the retroviral protease that contributes to AIDS in rhesus monkeys.

去份蛋白质折叠电子游戏（Foldit）的玩家就解决了逆转录病毒蛋白酶的三维结构这对猕猴身上艾滋病毒的治疗作出了贡献。

What we found was these protease levels are up to the same amount in vapors lungs as it's in smokers lungs.

我们现，蛋白酶的含量水平吸蒸汽电子烟的人的肺中与吸烟者肺中的含量相同。

Even more disagreeable is the fact that, along with ordinary house dust, we breathe in their feces, which contains enzymes called proteases.

更让人难以接受的是，同普通家庭灰尘道，我们吸入了“尘螨”的粪便，它的粪便中含有蛋白酶。

There's also pancreatic amylase which breaks down carbohydrates into shorter oligosaccharides, and proteases, like trypsin, which cleaves proteins down into smaller peptides.

另外还有胰淀粉酶，可将碳水化合物分解为小分子的寡糖；再者还有蛋白酶，如胰蛋白酶，可将蛋白质分解成小分子肽链。

These zymogens are normally activated by proteases which cleave off a polypeptide chain, which is kind of like pulling the pin on a grenade.

这酶原通过蛋白酶被激活，蛋白酶会将条多肽链切去，这有点像拉手榴弹的保险栓。

To digest a meal, these zymogens are released into the pancreatic duct, and delivered to the small intestine where they are activated by the protease trypsin.

当消化食物时，这酶原被释放入胰管，然后进入小肠，那里它们被胰蛋白酶激活。

Unregulated inflammation means lots of proteases, platelet activating factor, and free radicals floating around the gastrointestinal tissue which ultimately causes destruction of healthy tissue.

不受控的炎症反应意味着大量的蛋白酶、血小板活化因子和自由基胃肠道组织中流动，最终导致正常组织的破坏。

Second, even if a microbe produces collagenase and other proteases, enzymes that break down proteins, they CAN'T reach the collagen protein due to its interaction with calcium.

第二，即使微生物能产生胶原酶和其他蛋白酶，这酶可以分解蛋白质，但由于胶原蛋白与钙的相互作用，它们无法到达胶原蛋白。

Neutrophils make an enzyme called neutrophil elastase, a protease capable of breaking down elastin, which is an extracellular matrix protein that gives elasticity and strength to lung tissues.

中性粒细胞产生中性粒细胞弹性蛋白酶，该酶能够水解弹性蛋白；弹性蛋白是种细胞外基质蛋白，赋予肺组织弹性和韧性。

The cytokines attract Inflammatory cells like macrophages which start releasing even more inflammatory substances like proteases, platelet activating factor, and free radicals, all which contribute to inflammation.

这细胞因子可以募集更多的炎症细胞如巨噬细胞；这巨噬细胞进而释放更多的炎症介质，如蛋白酶、血小板活化因子和自由基，它们都可以进步促进炎症反应。

This means that their RNA is actually mRNA, and the host cell ribosomes use this mRNA to make a long polyprotein chain, which is then broken into smaller pieces by viral proteases.

这意味着它们的RNA其实就是信使RNA；宿主细胞中的核糖体可以用这信使RNA制造条长多肽链，随后被病毒蛋白酶分解成小片段。
