What is it about?
Alkaloids are a group of phytochemicals produced by a wide range of plants to protect them from disease and pests. They are active ingredients obtained from certain edible plants, such as coffee beans (caffeine, responsible for the bitter taste), and hot peppers (capsaicin, responsible for the hotness), and some are used medicinally, such as morphine. Certain alkaloids, such as strychnine, are toxic.

Why is it important?
Alkaloids can be used in medicine in their pure state, after industrial extraction. In therapeutics, they are used in extremely small doses and have a beneficial effect, but when the dose is higher, they can become very strong poisons.
Perspectives
Alkaloids are natural substances classified as secondary metabolites that contain one or more nitrogen atoms in the molecule, usually placed in a heterocycle. They present varied and complex structures, being compounds endowed with important pharmacological properties, and in large doses, they are more or less strongly toxic.
