alkaloid
Bitter plant compound
Alkaloids are nitrogen-containing compounds found naturally in plants, fungi, and some animals.
Many have potent effects on the human body—caffeine, nicotine, morphine, cocaine, and quinine are all alkaloids.
The word reflects their chemical behavior: like alkalis, they form salts when combined with acids.
The plant's alkaloids make it toxic to grazing animals.
