I don't think you can over apply peroxide.

认为你不能过度使用过氧化物。

So, when you pour peroxide on a cut, and it starts to fizz, it's not only killing bacteria — it's also killing some of your healthy cells.

所以，当你把过氧化物倒在伤口上，它开始发出嘶嘶声时，它不了细菌——它也会你的一些健康细胞。

As oxygen becomes pressurized, it forms large amounts of superoxide anion (O2) and peroxide (H2O2), which are highly toxic to living cells.

当氧气被施加压力时，会形成大量的超氧阴离子和过氧化物，这些对活细胞有剧毒。

For example, bleaching powder, bearing the chemical name calcium hypochlorite, contains chlorine, whereas peroxidase-based bleach doesn't contain chlorine.

例如，化学名称为次氯酸钙的漂白粉含有氯，而基于过氧化物酶的漂白剂不含氯。

" Is over applying peroxide to a cut bad? "

“在伤口上过度使用过氧化物不很糟糕？”

Peroxide kills bacteria by attracting the electrons from their cellular membranes, breaking the membranes open.

过氧化物通过从细胞膜吸引电子细菌，会使细胞膜打开。

That's mostly the peroxide reacting with an enzyme inside the bacteria, called catalase, forming water and oxygen gas.

主要过氧化物与细菌内部称作过氧化氢酶的一种酶正在进行反应，形成水和氧气。

So, peroxide will kill your cells, too!

所以过氧化物也会你的细胞！

I don't really use peroxide that much, except in that case like I mentioned of road rash.

并没有真正使用那么多过氧化物，除非在的道路疹的情况下。

But, when peroxide comes at your cells from the outside, the catalase can't protect them.

但，当过氧化物从体外进入你的细胞内部时，过氧化氢酶并无法起保护作用。

If you have a big open surface like road rash, peroxide can be good 'cause the bubbles can sort of rinse the little dust bits away.

如果你有像路面皮疹这样的开放表面，过氧化物可能会很好，因为气泡可以将小灰尘冲走。

They start generating highly reactive and therefore toxic oxygen-rich compounds such as peroxides.

它们开始生成高度活跃且因此具有毒性的富氧化合物，如过氧化物。

But as we age, there's declining levels of catalase, and this allows the build-up of hydrogen peroxide in the hair bulb, which damages and destroys the melanocytes, or the pigment producing cells, of our hair.

但随着年龄的增长，过氧化氢酶的水平会下降，这使得氢过氧化物在毛囊中积累，从而损害并破坏产生色素的黑素细胞。

Too much peroxide could actually dissolve my clothes, and some of my favorite shirts are in here, so we need to dilute this stuff to make the solution the right strength.

太多的过氧化物实际上会溶解的衣服，最喜欢的一些衬衫就在这里， 所以们需要稀释这些东西以使溶液达合适的浓度。

They could also identify distinct peroxisomes, small organelles involved in a metabolism, by staining for a protein called catalase, and it could map the precise subcellular localization of key functional proteins.

他们还能通过标记一种名为过氧化氢酶的蛋白质，识别出不同的过氧化物酶体，这些小型细胞器参与代谢过程，并能绘制出关键功能蛋白在亚细胞水平的精确定位图。

When mice were genetically engineered to not have any PPAR-delta- in their muscles, they couldn’t build endurance no matter how much they trained.

当小鼠被基因改造以使其肌肉中不含有任何过氧化物酶体增殖物激活受体δ（PPAR-δ）时，无论它们训练多少，都无法建立耐力。

Thus, a conductive copper layer is added next to the graphite, and a conductive aluminum layer next to the cobalt peroxide.

因此，在石墨旁边添加了一层导电铜层，在钴过氧化物旁边添加了一层导电铝层。

" It shouldn't be peroxide blond, obviously; it should be expensive blond, and then you get it cut in that sort of 'mum' haircut, where it's like a helmet." " You're being mean." Celeste tapped her lightly on the arm.

“显然，它不应该过氧化物的金发;它应该昂贵的金发，然后你把它剪成那种'妈妈'的发型，就像头盔一样。“你太卑鄙了。”Celeste轻轻拍了拍她的胳膊。

Since the dissolved peroxide creates even more water, the concentration of ions is quite low.

由于溶解的过氧化物会产生更多的水， 因此离子浓度非常低。

So the researchers admit that some athletes might be tempted to activate PPAR-delta with drugs instead of spending a whole lot of time training.

所以研究人员承认，一些运动员可能会被诱惑使用药物激活过氧化物酶体增殖物激活受体δ（PPAR-δ），而不花大量时间训练。
