And others, called reducers, lose them.

而还原剂则会失去电子。

We decided to try another reducing agent, vitamin C.

我们决定试试另种还原剂——维 C。

We saw that just like the other reducing agent, it in combination with isoniazid sterilized the culture.

我们看它跟另种还原剂相同，跟异烟肼这些细胞灭活。

Like, in this case, it connects the hydrogen sulfide reducers in anoxic sediment with oxidizers closer to the surface.

同样，在这种情况下，它缺氧沉积物中的硫化氢还原剂与靠近表面的氧化剂连接起来。

The important thing is that developers include reducing agents: chemicals that generally donate electrons to other compounds during a chemical reaction.

重点是显影剂里包含还原剂，它能在化学反应中给其化合物提供电子。

Jacobs was studying whether the TB drug isoniazid was being inactivated by the presence of a particular amino acid, cysteine, which in chemical terms acts as a reducing agent, by donating electrons.

Jacobs 之前直研究为何肺结核药物异烟肼会被氨基酸和半胱氨酸灭活，而异烟肼在化学反应中通过失电子，起还原剂的作用。
