Plant Secondary Metabolites: Structure and Function

Plant secondary metabolites (PSMs) are the hidden chemical arsenal plants use to survive, attract pollinators, and defend against pests. This course provides a clear, structural introduction to the fascinating world of plant secondary metabolism. You will learn to categorize the major compound classes and connect their chemical structures to their biological functions, preparing you for advanced studies in phytochemistry and natural products. What you'll learn: * Understand the definition and classification of the four main groups: terpenes, phenolics, alkaloids, and glycosides. * Analyze the basic biosynthetic pathways (e.g., shikimate, mevalonate, polyketide) that lead to diverse secondary metabolites. * Examine the ecological roles of PSMs, including defense mechanisms against herbivores and pathogens, and communication signaling. * Practice recognizing key structural features that differentiate major subclasses like flavonoids, sterols, and indole alkaloids. * Apply foundational knowledge to discuss the potential pharmacological and agricultural uses of common natural products. The content begins by defining core terminology and classification systems before moving into detailed sections on the biosynthesis and functional roles of each major class (Terpenes, Phenolics, Alkaloids, and Glycosides). Practical examples illustrate how these compounds interact within the plant and the broader ecosystem. This course is designed for absolute beginners in botany, biochemistry, and natural product chemistry. No prior knowledge of advanced organic chemistry or plant biology is required.
