Plant Secondary Metabolites: Defense, Chemistry, and Biotechnology

Plants cannot run away from danger, so they use a sophisticated chemical toolkit to survive and thrive. This text-based course introduces you to the fascinating world of plant secondary metabolites—the organic compounds that drive plant defense, communication, and adaptation. By reading this course, you will transition from understanding basic plant biology to identifying key classes of metabolites, explaining their ecological roles, and recognizing their modern applications in medicine, agriculture, and biotechnology. What you'll learn: Understand the core differences between primary and secondary plant metabolism; Classify major groups of secondary metabolites, including terpenes, phenolics, and nitrogen-containing compounds; Explore how plants use chemical signals to defend against pathogens and herbivores; Learn about modern extraction techniques and biotechnological applications of these compounds; Examine the role of secondary metabolites in sustainable agriculture and medicine. The course begins with foundational biochemical definitions and terminology before guiding you through metabolic pathways, ecological interactions, and real-world industrial uses. It is designed for beginners, biology students, and plant enthusiasts, with no prior advanced biochemistry required. Start reading today to unlock the chemical secrets of the plant kingdom.
