Usually it is synthesised either from methanol and formic acid, or methanol and carbon monoxide.

通常它由酸，或一氧化碳合成。

Some of these beetles can attack their prey by spraying formic acid from their abdomens.

这些虫中有一些能够用腹部向猎物喷射蚁酸。

Methanol is also processed by this enzyme, but the losses of hydrogens create formaldehyde and then formic acid instead.

也会被这种酶加工，但氢的损失产生醛，然酸代替。

The forage ants, for example, contain formic acid, so when you pop them, they taste like little limes or lemons because of the acidity.

比如，采集来的蚂蚁富含酸，所以当你食用时，酸的存在会让蚂蚁有种酸橙或柠檬的味道。

Substances like these aren’t intoxicating, they’re just poisonous, usually because your body metabolizes them into some horrible, dangerous compound like formic acid or oxalic acid.

像这样的物质不会让人醉， 它们只有毒，通常你的身体将它们代谢成一些可怕的、危险的化合物， 如酸或草酸。

That's why the buildup of formic acid in someone's body can cause a range of horrifying effects, from holes in the stomach and intestines, to vomiting blood and kidney failure.

这就什么酸在一个人体内的积累会导致一系列可怕的影响，从胃肠子上的洞，到吐血肾衰竭。

That's because your optic nerves — the nerves that transfer visual information from your eyes to your brain — need a lot of energy to function, so they're among the first to feel formic acid's toxic effects.

这你的视神经——将视觉信息从眼睛传递到大脑的神经——需要大量能量才能正常工作，所以它们第一批感受到酸毒性作用的神经之一。
