phenolic compounds

Phenolic compounds are a large group of naturally occurring chemicals found in plants. They contain a structure called a phenol group, which is a ring of carbon atoms with attached hydroxyl groups. These compounds contribute to a plant's color, flavor, and resistance to pests and diseases. In the human diet, phenolics—such as flavonoids, tannins, and phenolic acids—are valued for their antioxidant properties, which can help protect cells from damage. They are found in foods like fruits, vegetables, tea, coffee, nuts, and spices, offering potential health benefits through their biological activity.
