Secondary metabolites are organic compounds produced by various organisms, such as plants, fungi, and bacteria, that are not essential for growth or reproduction but play important roles in defense, communication, and adaptation to environmental stresses. These compounds often have interesting pharmacological, agricultural, or industrial applications, making them a focus of research in fields such as natural product chemistry and biotechnology. Examples of secondary metabolites include alkaloids, terpenoids, and phenolics. Studying secondary metabolites can provide valuable insights into the biochemical processes and ecological interactions of living organisms, as well as potential applications in medicine, agriculture, and other industries.
