和咖啡因一样,可可碱属于生物碱的一种,生物碱是相当大的一类分子,一般来说它的环中会包含至少一个氮原子,生物碱通常会使人类及其他动物产生生理作用。

动物世界

Sweeter chocolates have less theobromine, so the lethal dose is higher; about 5 kilograms of milk chocolate for dogs and about a third of a kilogram for cats, but they'd be sick long before eating that much.

动物世界

It's hard to know exactly why we evolved to be better at digesting theobromine, but it might be because alkaloids mostly come from plants, and our ancestors ate a lot more plants than early cats or dogs did.

我们很难确切了解为什么我们的身体会进化成能较容易消化可可碱,有可能是因为生物碱大部分都来自植物,而我们的祖先吃的植物比以前的猫和狗所吃的植物多很多。
