Acetaldehyde generates something called reactive oxygen species.

乙醛的存在会导致活性氧（ROS）的产生。

Fava beans contain compounds that when digested, boost the production of reactive oxygen species.

蚕豆富含促进消化的化合物，增强活性氧反应效果。

Overworked hair cells can also generate dangerous molecules called reactive oxygen species.

过度劳累的毛细胞也会产生称为活性氧的危险分子。

And a lack of G6PD can be dangerous, because the enzyme protects your red blood cells from molecules called reactive oxygen species.

人体缺乏G6PD会很危险，因为这种酶会保护红细胞，使其免受活性氧分子的破坏。

When mercury enters your system, it causes an increase in the amount of something called reactive oxygen species.

当汞进入您的系统时，它会导致称为活性氧的物质数量增加。

Lots of UVA radiation is also not great for you, because it interacts with other molecules in your skin to create reactive oxygen species.

过多的 UVA 射线也会对你不利——这种射线会与你皮肤中的其他分子反应，产生活性氧。

Finally, it's thought that high consumption and subsequent oxidative metabolism of alcohol might produce enough reactive oxygen species to overwhelm cellular defenses and damage the cells.

还有，大量摄入酒精及之后的氧化代谢可能会产生足够的活性氧，这会击溃细胞的防御机制并损伤细胞。

Finally, it's thought that high consumption and subsequent oxidative metabolism of alcohol may produce enough reactive oxygen species to overwhelm cellular defenses and damage the cells.

最后，大量摄入的酒精和随后的酒精氧化代谢被认为可能产生足量活性氧物质攻破细胞防御，而损伤细胞。

These cells stop producing proteins like antioxidants, so providing them with oxygen again can actually lead to the formation of toxic reactive oxygen species that they can't get rid of.

这些细胞不再合成抗氧化剂等蛋白质，因此在重新获得氧气时，细胞内可能会形成有毒性且难以被去除的活性氧。

While the human body secretes multiple enzymes to protect itself from these effects, under high pressure the production of these highly reactive species overwhelms a cell's ability to protect itself, destroying the cell.

虽然人体能分泌多种酶来保护自己免受这些影响，但在高压下，这些高反应性物质的产生压倒了细胞保护自身的能力，并最终摧毁。

Biochemically, this can tell repair mechanisms in your skin to speed up, so you get rid of stuff that was damaged by reactive oxygen species and make new cells and molecules at a faster rate.

生物学上说，这可以加快皮肤修复机制，使你能清除被自由基破坏的物质，以更快的速度再造新细胞核分子。
