Phytochemistry is the study of the chemicals found in plants, focusing on their structures, functions, and effects. This field explores various compounds, such as alkaloids, flavonoids, and terpenes, which play crucial roles in plant growth, defense, and interactions with other organisms. Understanding these chemicals helps scientists discover new medicines and improve agricultural practices. Researchers in phytochemistry analyze how these plant compounds can benefit human health and the environment. For example, some flavonoids are known for their antioxidant properties, which can help protect against diseases. By studying phytochemistry, we can unlock the potential of plants to enhance our lives and promote sustainability.
