This course will examine the biosynthesis, biological activity and ecological significance of secondary metabolites. Topics include: the links between primary and secondary metabolic pathways; an overview of the mechanisms, chemistry and coenzymes involved in the biosynthesis of natural products; the acetate pathway; the Shikimate pathway; the mevalonate and methyl erythritol phosphate pathways; the alkaloids; and chemical ecology. This course maybe listed as either CHEM 4435 or BIOL 4435. Credit cannot be obtained for both CHEM 4435 or BIOL 4435.
